Hey guys
I was wondering what Engine oil weight should I use on my 2000 TL with 140K
I always use full syntethic castrol 10-40
and my mechanic told me to use 5-30 I live in CA and the weather is like 90F these days
Thanks in advance

 

10w40 is way too heavy. Run 5w30 thats what the car recomends, you will be just fine. I run that on my 15k change intervals

 

You change your oil every 15K? Isnt that a little long??

 

Nope, not with synthetic. 3k is a big waste. even the manual recomends 7500. that motor had 200k on it and there was nothing wrong with it when i pulled it out. Even teh original machining marks were still in the cylender walls

 

so I need to use 5-30 all seasons??
Is 10-40 gonna damage or hurt the engine in anyway?

 

5w30 is what the car calls for. 10w40 is just too thick. its also probably hurting your mileage. You arent getting any added protection from it

 

i agree that the 3K intervals are BS...especially with the advent of synthetic oil. now, i schedule my oil change around my oil filter since that is the thing that needs to be changed before my oil does. BTW, i use mobil 5W-30 with a purolator oil filter.

 

so how often do I need 2 change my syntethic oil? every 10 k maybe?

 

thats would be fine. Make sure you are running the extended interval (it has teh yellow cap) its designed for 15k changes

 

What do u mean by yellow cap?
and what is the best full syntethic oil for our cars?

 

Mobil 1 extended performance, its designed for 15k mile intervals. The bottle has a yellow cap

 

Do you only change the filter every 15k miles too? The previous owner of my TL-S always used Mobil 1 Synthetic (or so I was told), so I want to keep in that tradition, but I've always used dino oil in the vehicles I've owned, and always changed filters when I changed oil.

Is the Purolator filter good for 15k? Are any of the other filters?

 

I used the fram extend gaurd filters and ran them the intire time. (i.e.. swaped them out every 15k)

 

royal purple, NG and redline make great syn oils. Mobil1 is veryo good too.

 

If thicker is really better, then why not use 20w50.

 

I second Micheal's comment. Honda made 5w20 the official oil in 2001. Yes it is for CAFE but there is no evidence to point to less reliability.

 

Ford has a very good article about the merits of 5w20:

https://www.fleet.ford.com/FFH/Why5W...sp?News=Rental

Anyways, the OP did not mention his location. One of the principal advantages of 5w-20 is the more rapid startup flow under ANY temperature in comparison to heavier weight oils, which can greatly reduce startup wear. The thinner oil can flow better and more dissipate heat more rapidly.

 

where can I buy Mobil 1 extended performance from? and how much a bottle?
thx

 

Just about any where. I get mine at wallmart. its the same price as teh other M1

 

i think the oil is $20

would a thicker oil make more compression?

 

Hmm. Fram says on their website that the Extended Guard filters are 7500 mile filters. I wonder if they get really plugged after 15k of use?

 

No. Hell If honda says regular dino oil and the cheap filters are good for 7500, there is no reason the extended type filters wont make it. Plus i have a motor with 200k on it with those intervals to back it up. It never burned a drop and my driving was very severe. the car idled all day

 

The Amsoil EaO is now the best filter you can buy on the market, followed by the K&N and Mobil 1 EP. These cost $15, $10, and $11, respectively. The K&Ns can be purchased on Amazon for about $9.50 each including shipping, provided that you purchase three at a time.

Even the orange can will last 15K in this engine since it's the OEM recommended interval, IIRC. Doesn't Honda recommend changing the filter at every OTHER oil change under normal driving conditions? All filters are built to meet/exceed OEM specifications and drain intervals.

 

Also, you can buy Mobil 1 EP, 5w30 from Walmart in a 5 quart jug. It's much cheaper than purchasing it from your neighborhood auto parts store. Cost is about $28 for the jug.

Pennzoil Platinum has also shown to be a decent synthetic oil, and recently, there have been many specials on this oil. It can generally be purchased for $3.00/qt after various mail-in rebates. You should be able to run this oil for 7500 miles with a good filter.

 

Use Mobil 1 5w - 30 $21 at Walmart and Wix oil filter $6. Plan on changing between 12k and 15k.

 

Autozone has a current sale on 5 quarts of Mobil 1 and Mobil Extened Performance filter for $30.
I bought a bunch of M1 5w20 last week, when I visited this week for something else, I noticed 5w20 are all gone.

www.AJUSA.com has the best price on K&N, $8.50 regular price for our car, free shipping if you order over certain amount. Subscribe their email alert and you will get email notice on promotions. I got 10% off 4 K&N plus free shipping couple months ago.

 

Thanks TunedTL. I went for the Autozone special, and bought the 5 quarts of M1 5w20 + M1 EP filter for $30 (no sales tax in Oregon ), which is a pretty good deal. Got the last 5 quarts too.

 

ive been using good ol conventional 10-40 since i broke 100k and havent had a problem idle is good, im at 132k now with 3-3.5k change intervals...

 

no need to run something that heavy. I ran 5w30 at 15k intervals since 100k and the motor was running perfect and didnt burn a drop when i pulled it out at 200k

 

No problem, ask for the "5 >$20 purchases get one $10 gift certificate" card at the check out stand. Show your receipt and they will punch your card, you are 20% toward another free $10.

 

In modern cars like the TL, running a lower weight oil is the norm. The main reasons are that the VTEC motors need a certain weight of oil to function properly. Those of you who remember the Oldsmobile Quad 4 motors know that running the wrong weight of oil had dire consequqnces for the cam lifters; the same can happen with modern cars. The second reason why is mileage - the lower the oil viscosity, the lower the drag of friction on the bearings and lower windage off the crankshaft.

For synthetic oil, you can go 7,500 miles per change, assuming you have no leaks.

Wix and Carquest (Wix) oil filters are the best ones that you can get normally - unless you want to find a race filter with replaceable elements. Purolator and the such are garbage - don't use them.

 

Actually, I'm going to play devil's advocate today (and open a can of worms) and say that Honda engines in regions outside of NA spec either 10w30 or 10w40 weight engine oil.

Purolator filters are fine, especially their PureOne line-up. Oldsmobile Quad 4 engines run fine on GC 0w30, AFAIK.

 

I noticed they don't sell the Mobil1 5w-20 in the big 5 quart jug, is that why you use the 5w-30?

Do you have to treat the engine in any specific way before going from conventional to synthetic?

 

No

 

Awesome thread. Still learning how to take care of my car. Mobil 1 Extended Performance it is!

 

FAIRFAX, Va.--Aug. 30, 2006--ExxonMobil today announced that Mobil 1 has been selected as the factory and service fill motor oil for the new 2007 Acura RDX luxury SUV.

Acura selected Mobil 1, the world's best selling synthetic motor oil, to meet the unique lubrication demands of the first-ever Acura turbocharged and intercooled engine. Due to its high-temperature
Based on its exceptional testing results, Acura recommends that RDX owners always use Mobil 1 5W-30, or an equivalent oil that meets the Acura HT0-06 standard. Not all synthetic oils meet the new Acura standard, and using the wrong oil in a high-performance turbocharged engine can lead to accumulated deposits in the engine, which reduces performance and causes engine wear.

 

OK. I am in NYC and I am gonna change oil around December when Winters starts. Would you say Mobil 1 5w-30 or 5w-20 ?

Does it matter if it Summer or winter?

Thanks

 

Here is difference in viscosity, little difference at high temperature but huge difference in low temperature (low does not mean winter)
Mobil web site published 5w-20 and 5w-30 viscosity spec for

ive never run any thing other than 5w30. You wont have a problem in the winter with it.

 

acutally they do sell mobil1 5w20 its just harder to find than 5w30 from what my professor was talking about in class 5w30 would provide more protection for the engine since its thicker. 5w20 being not as thick won't provide as much protection but the engine wouldn't have to work as hard which leads to better fuel economy. So its a trade off, more protection or more mpg
