well i did my oil change today and found out NAPA carries Royal Purple 5w20 now

car feels great!

allmotor_2000

What's your seat-of-your-pants feel here... just a smoother idle and feel for the motor or any kind of gains?

mattg

i'm about to do my first Royal Purple oil change myself, it was only like $6 bucks more (total) than mobil one.


i didn't know it really was purple

mattg

allmotor, if the weather holds i'll be at the track in a few hours. we'll see if the car feels any different.

gregshin

how much was it per quart?

allmotor_2000

If the damn thing is $6 more... its totally worth it. They claim dyno gains of 1.5% to 3% (at the wheels), so for our cars, that's 2.5whp to 5whp.. not bad I suppose!

sidemarker

well at a local performance shop they sell it to me for 5 bucks a quart. I believe I paid about 6 per quart from NAPA

I dont know if its just me but when i first started the car it actually felt a lot smoother and idle is a bit smoother too. As far as performance is concern cant really tell yet

Ive been using Royal Purple 5w-30 for about 25k miles and this is my first time running 5w-20, after i put a couple hundred miles ill give everyone an update.

I am really excited because this is my first time running 5w-20. So only time will tell if its any better then 5w-30

NOVAwhiteTypeS

hmm shouldn't u be using 5w30?

allmotor_2000

There's only a very slight viscosity difference (across all temps) between the 5W20 and 5W30. You 'might' have some blowby at high rpms with the 5W20... so check your crankcase vent

sidemarker

im surprised you havent used this stuff when you had the turbo

I heard that Royal purple was perfect for FI motors.

Well with the 5w-30 i was running i couldnt tell. the only reason why i switched to purple is because my friend and I tested this stuff out. a few years back my friend and I both had an accord v6. we had all the same mods but his car was always a little faster then mine. he was running the purple stuff and i was running on quaker. surprise suprise when i switched to RP the outcome of our races was about dead even

sidemarker

thats what i thought but in the 02 manual and the oil cap they both read 5w-20

sidemarker

mattg

my (01) oil cap says 5w-30.



:edit: read this link from the other oil thread

School me on this..I thought 01-03 were the same motor! My manual says 5W-20, but I run 5W-30 Mobile 1...

Wish I would of read this post before I changed my oil this morning..and friggin NAPA is right next door to my gagrage!!! damn it..

mattg

Smitty, read that link i posted above.


it does say 5w-20 in my manual, but 30 on the cap.

jts1207

so 20 or 30

sidemarker

at this point it dosent matter. ive used 5w-30 for about 25k miles. this is my first time using 5w-20 and summer is coming up so ill see how well it does for mpg and performance...

sidemarker

jts1207

so try 20 in the summer?.............where is the best palce to buy it?

mattg

imo, 20 would be better in the winter, 30 in the summer.


obviously noone read the link

vuduvida

I read that link and IMO, it's a good example of why I won't use Amsoil- they try to generate hype. I'm sure Amsoil is very good quality and I'm not going to argue with the pro-Amsoil crowd- just my opinion. Personally, I think Ford and Honda have quite a bit to lose if they recommend the wrong viscosity. I'll stick with a good quality 5W20 (even in hot AZ).

sidemarker

well you cant go wrong with 5w-30. im just testing out 5w-20. i think you can go either way but i HEAR 30 is recommend during the summer, but 20 is fairly new stuff.

Are you refering to royal purple? well NAPA carries both Mobil 1 and Royal Purple if you plan on going synthetic.

i went 7000 miles with 5w-30 in about 5 months and had no problems. the only thing i worried about was the oil filter. I am using the honda filter and i think you are suppose to replace it every 3k miles??

Also if you plan on going with the Honda oil filter buy it from a honda dealership (its the same filter for the accord) you will save a couple bucks

This is why I run a mixed ratio of 0w-30 and 5w-30 Mobil 1.

1qts 0w to @4qts 5w in the summer

2qts 0w to @3qts 5w in the winter

You can tell the engine revs a bit quicker and gas mileage is better. I've been doing this since the 3rd oil change and I've had my 02 TLS for over 2 years now.

I only trust doing this with a premium synthetic.

kHmER Co

a friend of mine told me royal purple isnt good for daily driven cars, ive used this before, and there was no noticable difference comparted to the regular dealer oil, ive alse used redline for a while, i would say redline is better, but who knows? i wonder what a dyno comparison of the two top notch oils would prove.

mattg

so what about the fact that amsoil makes 5w-20 as well as 5w-30?

how would the article benefit them?

fender4

There is always some that will hate Amsoil,, Exon/Mobil ect ect ,,,
I started out trying to find the best synthetic using lab tests,, I didn't even know about Amsoil,,( I still can't find anything better (Mobil1 is close) and the plus side Amsoil is the only manufacture that tell you NOT to change your oil every 3-5 k miles,,, I have a continue test going on my car,, I change every 10k, filter every 5k,,, so far buy lab analysis, the results have said not to change it even at 10k. Simplistic results are TBN number 7.xx,, most brand new petro oil is around 8.xx. No matter what part of the country your in 0w30 or 5w30 will work fine. Another plus is Amsoil will warranty your engine if their oil has failed.

More fun reading,,,,,

Yes all pro Amsoil but note all the lab results have not been challenged/disputed by Mobil

http://www.desertsundirectsales.com/...vearticles.htm

And yes I pay Amsoil $ 20 a year so I can buy it wholesale,,, Anybody can do this,,,

sidemarker

fender4

do you use 5w-20 or 5w-30?

so with amsoil you change every 10k miles and filter every 5k miles. how much more oil do you put in after you change out the filter?

sidemarker

vuduvida

it benefits them by generating hype which gets more people to visit their site (just like you were directing people to that link). Their marketing plan is close to that of a MLM- individuals who sell it people who then may be recruited to sell it themselves.

Take a look at that link fender4 posted above and you'll see articles like "Increase Your Income!!" and "Home Businesses are Booming!"- trying to get more individuals to sell it, similar to Amway tactics. They bash other companies with quasi-scientific articles which then gets more people talking about them. They bash K&N filters and Harley-Davidson’s oil at that link above- both articles designed to generate hype. Their marketing practices seem far from professional but again, I'm sure their products are very good quality

No, Red Line Oil is another company that suggests long drain intervals. Here's their quote:

"Red Line recommends oil changes for engines that are in good condition and do not see frequent starts without warm-ups or short-trips at between 10,000 and 18,000 miles for gasoline engines, 10,000 and 12,000 miles for diesel engines, or every 12 months, whichever is shorter."

russianDude

I think all synthetic oils are approximatly the same..... Just get a good brand synthetic oil and good filter.... and you will be allright for 5-6K miles....

mattg

the fact that my oil cap ('01 cl-s) says 5w-30, and danny telling me the the '02 and '03's say 5w-20, falls right in line with what the article states.

dunno if it's true or just hype, but it is a coincidence.

vuduvida

the hype part is just my opinion- I may be completely wrong. My gripe with them is their marketing tactics, not the quality of their oil. I just don't see Honda and Ford recommending an oil that will end up causing pre-mature engine wear since there'd be a huge class-action lawsuit (who knows though...). My car will be long gone before that would ever happen though. I'm using 5W20 to get the benefits of a thinner oil (minuscule increases in performance and MPG) since I think the brand I use offers plenty of protection.

russianDude: there are different qualities of base stocks used in creating synthetic oils. That's one reason why Mobil 1, Syntec, et al cost about half the price of Red Line, Amsoil, etc.

russianDude

I am very skeptical about Amsoil or Red Line..... if they are so good, why aren't they sold in Pep Boys or other Auto stores?
regardless, I think Amsoil is over rated..... they bash on Mobil 1, and claim they are superior. Even if Amsoil is a little better than Mobil 1, I am sure the difference is very small.... like Amsoil pours at -55F and Mobil at -50... do you really care about that? Is it worth paying so much extra $$$? Another thing I hate about Amsoil is that they keep bashing on Mobil 1.... its just unprofessional.... just my oppinion....

the bigest benefit for your engine is a good filter that you change often....... i'd say all well known brand synthetic oil are pretty much the same ( with some settle differences which are really small for an average user ).
If you do some crazzy ass stuff like racing and etc, then you might want to look into Red Line or other stuff....
Don't worry about oil so much, get yourself high quality filter like Mobil 1, Puralator, or Amsoil filter

vuduvida

ah, somebody who agrees with me about Amsoil

I can buy Red Line oils at several shops locally but I buy it online since it's cheaper. Pep Boys near me sells Red Line products- at least I've seen their Water Wetter and Fuel injector cleaner there. They probably don't stock their oil since they feel they wouldn't sell much- it's not cheap.

I agree these oils may be overkill for the type of driving our cars see but I don't mind the extra cost since I do the oil change myself.

fender4

for this thread I recommend 5w20 and change it every 3 k...

Please post any "quasi-scientific articles" tinman???,,,, also mobil1 ads quote that they are the best ,,, but using "real" science they are not,,,, they are marketed for the individule salesman but it seems to work,,, they just became the sixth largest oil company,, and this is without having any gas stations on the corner...
again if your comfort zone is 3k changes so be it,,, I mixed and changed every 3k for 4 years. Sorry if amsoil marketing "bugs" ya but remember they are a profit making company,,, just like like dare I say Mobil,,,

vuduvida

relax- I said Amsoil is a good quality oil, and I don't think my comments were the first time you've heard somebody gripe about their marketing tactics...

but, how about the article that prompted my original comment: where's the scientific proof that using 5W20 will cause a late-model Honda or Ford engine to wear out sooner? And that the only reason Honda and Ford are suggesting to use it is for their own profit?

I don't use Mobil 1 and my change interval is not 3k I use Red Line and I change around 10k

jts1207

now that you mention it amsoil does sound like amway

fender4

or MARY KAY,,, don't forget Tupperware,,,, tons of good products
marketed this way,,, dif between amway,, they use a high dallor +500 to become a salesman,, this is then split between the pyramid,, makes for selling "salemans" and not the product,, used to be this way,,,

RUF87

Sounds like you all need more choices. :P

Anyway, if I remember correctly, a resident expert on lubrications on the TLS Forum rated Redline the best over all, but that a new one has come out and taken over the top spot.

Of course you need to note that as improvements are made, so do the rankings.

Here is a link to most recent engine oil champ according to Road Rage's reviews.

Yes / very good for $20/qt/ and they recommend changes every 7500 milles. There is better at $30/qt,,, ???? again yes these examples are used for racing engines that are ussally rebuilt every 500 miles or so, run at 7-10k rpms and NOT used as daily drivers,,, which they need to be for true comparisons by lab analysis,,, again at $20/qt,,

RUF87

Actually, it's not that pricey. Especially if you by it by the gallon or 2.5 gallon container.

It's $7.00 or less that way. Of course you need to add shipping and tax.

Sorry to open up dead threads. Do not use the 5w-20 oils. They are way too thin to properly protect your engine even with Amsoil or Redline. 5w-30 or 0w30. Amsoil's 0w30 flows at 112 below 0 so flow isn't a problem.

fender4

on the below web page they list 0w30 Amsoil at -76

http://www.unofficialbmw.com/all/misc/all_oilfaq.html

-112 needs confirmation
