AMSOIL vs Mobil 1 Synthetic???

[cthirtysizzle]

Hey what's up everyone, haven't posted in little while. So I have a friend who was one of the first people to buy a C36 in late 1994. Since he bought his car he's been using AMSOIL and recommends that I use it as well. I have a 97' C36 as you all know, but I don't know too much about AMSOIL. I do know, the guy I bought my car from told me that he's been using Mobil 1 Synthetic 0W-40 since he bought the car, so that's what I've been sticking with. AMSOIL recommends using their AMSOIL 5W-40 european motor formula and supposedly you're only supposed to change it every 10-15k miles... Any input?

Did you see Amway's oil on M-B's approved list of oils ? :rolleyes:

AMSOIL is extreme! They are designed for DIESEL app. orginally. I got the chance to get to know some of the AMSOIL guys from all the shows we did. They rock!

DISCLAIMER - I do get them for almost nothing. :D :D I might be biased!

Some of the best oil out there now is the Castrol 0-30wt Syntec oil, the stuff Made in Germany. You need to make sure it says that on the bottle. The USA made oil is not as good.

and award goes to mista c280 up there.
u know wut i agree with u too on synthetic versus regular oil.
now when u have time can u look up which oil is used from factory for 95 C36

1995C280,

I can't agree with much of your post, however if you want to run petro oils go ahead.

But, I think all of the current data on oils show that synthetic oil out perform conventional oil in every catagory.

I run, as stated before either the German Castrol Syntec 0-30wt or Mobil 1R 0-30wt. The Mobil 1Racing is a new oil and can be hard to find.

I'll have to get back to your post, as soon as I finish changing my pants.
I laughed so hard..............I pissed myself.
20 psi difference from one cylinder to another?
You've been flying on the starship Enterprise too long. :rolleyes:

1995c280,

Gosh, I dont know where to begin.

Reduction of 200degree in engine is GOOD! Of course the thermostat won't open as soon -- There is NO NEED to. As long as, the engine is in close loop anyway, it is working JUST fine!

And you could've figured that if you have PSI drop in the wet test, you do have leaky/woren out piston rings. You can use either oil, you still have bad piston rings.

The probable reason why your compression is better after using petro based oil is because unlike synthetic oil, petro oil gets thicker quickly and prevented the compression to leak down through your bad rings -- hence the more stable readings. This is why many of us use 'thicker' & 'heavier' oil on OLDER cars.

For the other zillion reasons, Synthetic is better !

Thanks for clearing that up Ken, :)
Btw, how's that turbine system comin' along? So what do you recommend, Mobil 1, German Castrol, or AMSOIL?

[Luwin1026]

German 0-30 Castrol Syntec here and loving it, and I was a Mobil-1 believer as well. Both are great, but my Honda seems to be liking the Castrol.

1995C280: Funniest post I have read in a long time, your errors were already corrected in another post so I won't bother, but you gave me a good laugh

mobil 1 has high standards recommended by amg,porche etc.. and they promise to ends uo engine wear,recommended.

all of you are forgetting... Synthetic Oils taste better too!

Synthetic Rocks!
Mobil 1 DTM powah!

[marksbenz]

Mobil 1 15W 50.

[redc36]

just got mobil 1 Racing 0w30
i will let u know if i feel a difference guys

tried amsoil and mobil 1 before. amsoil on cold starts makes my engine sound louder like more ticking noise. i didnt like that. as a matter of fact my engine sounded louder even when it warmed up. so i switched to mobil

now its time for mobil racing

I've had good luck with previous cars running Royal Purple. In fact, its the only oil I've ever seen Hot Rod magazine actually endorse as adding measureable H.P. on the dyno. Doesn't matter what oil you use if you don't change it!!

[coolcarlskic43]

Amsoil Euro synthetic 0W40 all the way!Even in the tranny and diff.ATF that is and gear oil.Amsoil!!!

[nikrox]

i agree......amsoil european formula is the best.ive used it for years, and theyve proved its better than mobil 1 or royal purple

mobil 1 is better than royal purple, but amsoil is still #1-and you can go roughly 7,500 miles before roccomended oil change.ive had friends go 10,000 miles and it still came out good and clean.so with all those oil changes it actually saves you money by buying amsoil, cause it lasts longer

not only personal preference, but proven fact
