Peruse this forum.

too much nonsense no cut and dry comparo's

 

Ive been told that Castrol is the only approved motor oil for turbo engines- and is best suited for Imports-

Mobil 1 is best for domestics....

Like I said thats what I was told buy an oil rep for NAPA- Anyways thats my .02...

 

What are the differences between domistic and imports? Sounds like a line from Castrol.

I use Mobil 1, works great.

 

Imports; Honda, Toyota, Scion, Lexus, Acura, ....

Domestics; Chevrolet, Ford, Dodge, Chrysler.....

The guy said Mobil 1 is good for anything, But Castrol is better for imports, and higher revving engines ( hense impports )

 

I've been using valvoline synthetic.. Just to be different.

 

lucas http://www.lucasoil.com...but between the two you listed ill take mobil

 

I know the difference between an import car and a domestic car. My real question is what is the motor difference between the two. I have always heard that imports rev higher, I don't believe that. Any 4 cylinder car will sound like it rev;s. higher, but does it really.

Most cars that I have owned highway cruise at approx. 2300 - 2500 rpms, that was 8cyl., 6cyl., and 4cyl. I owned a 73 340 Duster with 3:23 rearend and it cruise at highway speed at approx. 2500 rpms and during my normal excelleration would shift at approx. 3500 - 4000 rpms. If I romped on it this shift change would happen between 5000 - 6000 rpms and if I manually shifted the automatic I could crank her out to 7000 rpms with no problem.

My Xa is the first import car I have ever owned and on normal excelleration it shifts at approx. 2500 - 3500 rpms and has a highway cruise at 60mph of just around 2500 rpms. How is this import any different than any other car?

Many NASCAR owners use Mobile One and they turn over 9000 rpms during a race.

I guess what it comes down to is everyone has a different idea on what type of oil to use and the oil companies will tell you anyting to sell you their oil. Pick the one you want and if you change your oil regularly you won't have any problems.

 

Ok... I had this whole debate before along with the debate about using synthetic in the first place. There is a website - I believe it's something like www.bobtheoilman.com or something that does actual SCIENTIFIC comparisons. It's vaguely technical and has a lot of charts and stuff, but I can summarize quickly for you:

IF YOU REALLY CARE ABOUT YOUR CAR ENOUGH FOR THE SLIGHT ADDED BENEFIT OF SYNTHETIC TO BE WORTH THE MONEY, THE ONLY ONE TO USE IS MOBILE1. The chart proves it. There are really only two things that make synthetic worthwhile. One is less viscosity breakdown over time (which oil lubricates well for the longest) and frankly I can't remember the other point. Anyway, find the site and read it if you don't trust me. Mobile 1 (I buy it at Costco) is the one to use.

 

Royal Purple all the way!

 

The only true synthetic oils are Amsoil (my preference), Royal Purple, Redline, and Mobil 1. You can't go wrong with any of them and they kick the tar out of Dino oil. and are less expensive than Dino oil to use overall when you consider the extended drain intervals... Do your research

 

Can you provide me with some truly INDEPENDANT research? I'll give you some food for thought; I raced motocross for 27 years and came to know a lot of guys in the process. In 1997 a friend of mine (not Mike LaRocco) had a sponsorship deal with Amsoil. Got free product, cash, ran their logos and such, and one day we were at a race in Ok. and I watched his mechanic pouring Yamalube 2R in some gas and Silkolene in the trans! I asked him about this quietly and the mechanic stated that they had tried the Amsoil products and had experienced scuffed pistons and cluth slippage. Granted this is only one guys opinion (and I can't vouch for his intellegence level), but there are so many OPINIONS out there that some concrete comparisons between brands of oil would be interesting. The testing I am referring to would be provided by an INDEPENDANT source that has no ties to or was not hired by any oil company. This would indeed be interesting.

 

i use castrol 5w30 part synthetic.... made big difference in idle and accel

 

Royal Purple...Never turn back! Been running it in my Tacoma for a long time never had any problems. And Duh.......It fickin Purple

 

http://www.bobistheoilguy.com/ is the site I mentioned above. They have forums and stuff now. I didn't see what I was looking for right away, but if you're ACTUALLY looking for your real research, go browse. I can't vouch for the forums, but the articles and info on the left side bar is good stuff.

 

ok I would be happy to school you!
