Whats the best Synthetic Oil

I have almost 7,000 miles on my 07 TL-S. What Synthetic oil would you

suggest? Also should I start doing my own oil changes? Years ago I use

to do all my oil changes because of saving $$$. But the last 15 years I

have always had the dealer do it so it was on record there.

Besides going Synthetic engine oil, I would like to change the trans to

Synthetic also. I have an automatic. What do you suggest here???

I think its best to have the dealer do the trans, but any opinions on this

is welcome. Many people say they don't let the dealer do ANYTHING on

their cars. I can understand, I have read MANY HORROR stories about

dealers nowadays. Thankyou very much Jeff D.

I personally use Mobil 1 synthetic, but im sure everyone has their own opinion on what oil type to use. I would recommend also using a honda/acura oil filter when you do your own oil changes. As for the trans i would stick with honda/acura ATF you can use other stuff if you like, since you have a new car i would stick with acura stuff for warranty purposes. As for taking the car to the dealership, i work for a honda dealership and do all the work myself and make sure it is done right. if i didnt work for a dealership i probably wouldnt take my car there anyways because i am soo damn anal about my car, i would do the work myself at home!

The Mobil 1 is no longer the good stuff- formula changed to cheap tier

Penzoil Platinum FULLY synthetic- 6$ something per quart
look for those words FULLY Synthetic
is working very well in my 01 TL and K&N oil filter is my choice $10-12

I was looking at the Mobil 1 bottles and they all say Fully Synthetic....

Do you have any articles to back up the fact that Mobil 1 is no longer good stuff?

go to their website the new high mileage is the old mobil 1
mobil 1 now uses lower grade base oil
you may have found old stock of bottles and formula
changes in EPA requirements on oil additives forced several brands to change

I checked the web site and I think you are mis-interpreting the information.

Although Mobil 1 is not their top tier product, it still is a full synthetic product. The other good thing is that I saw the 5qt container of 5w-20 at Walmart for around $19.

The info I looked at is here:

http://www.mobil.com/USA-English/Lub...il_1_5W-20.asp

Product Description

Mobil 1 5W-20 is a high performance fully synthetic engine oil designed to exceed the industry's toughest standards and outperform all conventional oils. Mobil 1 5W-20 is engineered to help keep your engine running like new and extend engine life. Mobil 1 technology has been selected as original equipment by leading car builders such as Chevrolet Corvette, Cadillac, Mercedes Benz AMG, Porsche, Dodge Viper, and Dodge Ram SRT 10.

Applications

Mobil 1 5W-20 is recommended for all types of modern vehicles where this viscosity grade is recommended. This includes high-performance turbo-charged, supercharged gasoline multi-valve fuel injected engines found in passenger cars, SUVs, light vans and trucks.

* Mobil 1 5W-20 is general purpose engine oil for all types of cars where this viscosity is recommended including Honda, Ford, and other major carmakers
* Mobil 1 is not recommended for 2-Cycle or aviation engines, unless specifically approved by the manufacturer.

Can't go wrong with Mobil 1.

That having been said, I have always been a Castrol man when it comes to imports. I usually go with their syn-blend (forget the name) which kind of splits the difference in price between their full-syn (which tends to be higher than Mobil 1) and their dino oil.

But, last time I was in Wally-World, I was checking prices on full-syn and the new Penzoil is the cheapest by about $2 on the 5-qt. Castrol is still highest. I may try the Penzoil Platinum next time around, if they have the 5W-20.

I use Royal Purple. Best thing I have ever done to the car. Runs so much smoother. I use 10W 30. I got 68K on my car and a little more protection never hurt. You should try it.

Why do you prefer 10w30 instead of the recommended 5w20 or previous 2G recommended 5w30?

not smart to put heavier weight oil...you are hurting your car more than you are helping...honda designed that motor for 5w20..the oil passages through the motor are sized to allow the appropriate flow for 5w20..you put 10w30 in..its not gonna flow the same...for an example
A coffee straw is made to flow coffee through the way it should, a normal sized straw would be appropriate for a milkshake...what happens if you drink a milkshake with the coffee straw? Little or no flow will occur...this is just my

if you want the best synthetic oil, you would have to go to the back end of the auto store and they'll hand you the best synthetic oil~!

I run Mobil 1 in the TL. Bought a couple quarts of the 5-20 and a few of the slightly heavier stuff, can't remember the exact viscosity. I'm currently in Vegas and it's hot as hell around here. Will go back to straight 5-20 when it cools off.

In the turbo car I run regular oil because it sticks to parts better over time and I only start the car every few months. Plus I change the oil every 500 miles so there's really no reason to run synthetic. For whatever reason, everytime I've torn down a motor, they have less wear with the regular oil. With the same weight oil, I have more oil pressure with regular oil and on startup the pressure comes up quicker.

So each of us loves the oil we run and think its better than all the others

Blackstone Labs gets asked whats the best oil all the time

They run DINO oil in all their personal engines...

synthetics extend change interval providing you perform a good engine internal cleaning- seafoam the crankcase- first
then 10k or more on fully synthetic ask fsttyms1

By DINO, are you referring to regular, not synthetic oil? I've flat out had better results in the Buick with regular oil. I switched to synthetic for a shot time because the turbo superheats the oil but switched back after a teardown.

I agree with your post but I have a problem going that many miles on an oil change. I haven't heard of the Seafoam internal cleaner but it doesn't sound like a bad idea. Every few oil changes I will buy the $.99/quart oil and run it for a day and then change it again with synthetic, sort of the same thing.... kind of.

While the synthetic may not break down as quick, at 10,000 miles you are going to have all kinds of contaminates and fuel dilution not to mention the filter is probably being bypassed.

Those of us on long intervals probably change the filter and take an oil sample to be tested

Dino oil is regular oil which is fine for most cars and applications

Azine members seem to want the very best for their car so run synthetic

the built in oil reminder on your car doesnt go off for 7500 miles

read up on seafoam= lots of converts and believers here!

I do prefer regular oil in the 600hp car.

I don't care what the oil reminder says. An internal combustion engine is an internal combustion engine. It's still going to contaminate the oil and dilute it with gasoline.

Who is fsttyms1 ? How do you do this Seafoam flush? How much is used?

How exactly is this done. I had my first oil change done @ Acura at about

4500 miles. I have 7000 miles now and want to change to Full Synthetic

myself. Also how do I zero out the computor? So its back to 100% ?

kris is fsttyms1 = fast times won! He is Moderator-resident guru of gen2
look in the gen 2 thread Seafoamed the Ol TL for complete details
Its the same stuff used in the $129 fuel induction Service at dealer except we do it better 10-15$ total parts and 30 minutes of your time including a freeway blast to clean out the carbon afterwards...Finally a repair thats fun!

Check owners manual or search gen3 for oil minder reset instructions- on gen2 it involves holding 2 trip reset buttons and turning on the key

Which oil and filter did you choose of the dozen offered as suggestions?

I also did my first oil change last week. I did some EXTENSIVE research on the forum on things like "when to do your first oil change", "what brand of oil to use", and "what weight of oil to use"?

I suggest you to read the following threads and pay special attentions to posts by RoadRage and SodaLuvr. I believe they're oil gurus. (BTW, these threads are all from the 3G garage.)

https://acurazine.com/forums/showthread.php?t=111549
https://acurazine.com/forums/showthread.php?t=111590
https://acurazine.com/forums/ramblings-12/great-trance-track-111490/

FYI, I did my first oil change at around 5K miles and used Mobil 1 Extended Performance 5W-30. I would have used 5W-20 if I could find a 5-quart jug here in Vancouver.

Good luck!

The K&N and Mobil 1 filters are highly rated and way better than OE

Penzoil Mobil Redline- take your pick as long as the bottle says FULLY synthetic

5-30 is better for our engines- the 5-20 was a way to scrape a tiny increase in mileage from the engine DURING EPA test for some govt regs about corporate average across the models-
the 5-20 offers less resistance but the 5-30 is better for engine parts

I can tell you from experience that I put Mobil 1 10W-30 in my TL at the first oil change and my average MPG dropped one (1) from 22 to 21. I think it feels a little less "snappy" but that could be all in my head.

Road Rage likes a 30 weight oil with as little spread between the summer and winter ratings. E.g. 10W-30 because used oil analysis show it holds up a little better against shearing because of fewer VIs (viscosity improvers). RR holds that Honda/Acura recommend 5W-20 because the Feds make them recommend what they used in their fuel economy and horse power rating protocols. He feels that, if not for that, they would prolly recommend 10W-30 like most car mftrs in this country. Note that in Europe, the performance autos usually recommend 10 or 20W-40.

That made sense to me so I followed RR's advice and, in addition, followed his other advice to add 15 oz. of Valvoline MaxLife Engine Protector to the Mobil 1 for its molybdenum content. Honda/Acuras come with high moly content. The factory warns in the owner's manual not to change the oil before the MID says to because it is "special break-in oil." UOAs show the only thing special about it is the high moly content.

In fact, the Havoline that you bought happens to have almost the same moly content as the factory fill from Acura and is a highly reputed oil. You can't go wrong with either 5W-20 or 5W-30. They are both good. Their thickness or viscosity is quite similar. In higher heat and stressful operation, I would feel better with the safety margins of the 5W-30 but it's a matter of personal preference. Neither will hurt the TL. You might give up a slight edge on the fuel economy but I doubt you would notice it. It might amount to an extra 5-10 miles range per tankful. Maybe.

Equally important is to get a good filter. Mobil 1, Purolator Pure One, are good. Stay away from Fram IMO. Their construction leaves a lot to be desired. That's my personal opinion and not that of Acurazine.com.
I drive hard and that is why I use Royal Purple 10w-30 w/ K&N filter.

Isn't Redline Full Synthetic oil a Honda product??? Wouldn't that be best?

I am going to see where I can get Royal Purple and Redline. And I will check for the K&N

oil filter also. I am worried Mobile One isn't as good as it use to be.


As for the Seafoam flush b4 changing to Full Synthetic, I don't need it, my car has only

7,000 miles on it. I don't think its carboned up yet. I just put a pint of Seafoam into

about 10 gallons of gas. I will run out that fuel then just change my oil and filter.

This should be fine,,, Correct ???

ONE more thing,,, I think I should get 5w-20, I don't want a thicker oil, I think

5w-30 might be overkill. What do you think of this ???

Most are obsessed with heavier weight oil, which is overkill, and not needed this day and age with the oils available. Stick with the recommended viscosity.

The Z06 Vette comes with Mobil 1 5-30, and if you deviate they will void the warranty. Even if you use the Mobil 1 Extended Performance 5-30 GM will void the warranty.

This in no way is to indicate that Honda/Acura will void the warranty should a substitute be used, but just to indicate that the oil recommended by GM is mandatory and not be altered.

Just my

I use Pennzoil, though as I've mentioned several times, I use it because I don't pay for my oil changes. I've also used Mobile and would probably use it if I wasn't getting the oil for free, though I'd rather kill myself than shop at Wal-mart so I'd have to come to terms with the high price at the auto shop.
