Hey, you are the one that brought him up, buddy, not me LOL.

GreekGator

just out of curiosity, how much is a qt of Amsoil and a qt of RP?

Absolutely, my point for recommending the search was the amount of technical information Patman has presented and the things to look for in oils as a whole.
My reasoning for this was to help the original poster gain information for himself so that he can form his own opinions with solid information. Not neccessarily to just run out and grab whatever is recommended in this thread or that.

you're confusing moly coating (the thing that makes the oil soooo damn good) with varnish.

understandable since it does leave a yellowish tint on everything.

if you do some research on moly coating and synthetic oil, you'll find some interesting info. i wont bother trying to describe it myself, since i cant describe nearly as good as others. my English is the suck this morning.

I always put oil in my 622 race motor filter before installing, but have never done it on my LS1, although it makes sense to.

I wonder what his reason was for recommending 0W-40 over 10 or 5W?

Mobile 1...seems to be just fine under many different types of driving.

Patman

I don't recommend Mobil 1 0w40 over 5w40 or 10w40 actually, but a lot of people misquote me on that. A long time ago when Mobil 1 only offered a 0w40, but no 5w40 or 10w40, I would tell people if they had to run Mobil 1, that the 0w40 was a better choice over the 5w30 or 10w30. But Mobil 1 0w40 would not be my first choice by a longshot. Their 5w40 Truck & SUV would be my first choice of their oils, followed by their 10w40 Extended Performance.

I'm not a big fan of Mobil 1 oils though, but I know there are a lot of people on here who will run nothing but Mobil 1, so I had to give them some sort of better choice than their super thin 5w30 (which is almost a 5w20)

Patman

Not true, if I were to choose a runner up to German Castrol 0w30 it would be something like Amsoil 5w40 or Redline 5w40 or even Castrol's 5w40.

I am again reminded of the complexities of the "which oil to use" question, which is determined by various factors such as, is one trying to make the most power or to maximize engine life. The answers to such quetions will determine which oil to use. Thinner oils will make more power, but reduce engine life. The inverse is true for heavier oils.

that is SOOOOO not true.

think about this:

we can all agree that the most engine wear occurs at startup, when the engine does not have the full VOLUME of fluid running thru it yet.

a thinner oil pumps quicker and can get into the bearings sooner.
a thicker oil will show PRESSURE sooner, but takes longer to pump around the motor.

sitting overnight, they both will have runoff.
if they're synthetic, both should also leave a rather good film on the parts anyway... so the amount of oil remaining is almost identical.. just because its thicker does NOT mean more oil will stay on there....


in most real life situations, it turns out that the quality synthetic thinner weight oil actually protects better then the thicker oil... even though it reads a lower pressure at times.

Race Car Driver

MrDude,
We have dyno'd our engines, such as our 622, and tested everything from 10W30 to RP racing lite, and there a 20 hp range between these oils. So, it really is sooooooo true that lighter oils make more power.

if you read what i wrote and not just the first part, you would see that i never disagreed with that.

Only ran 10w 30 Rp in my ls1 since I have had it....had a 91 mr2-t only ran Rp once I got it.....never had any problems with either....never had oil loss/burning issues, only possitive results....and strong running engines. Just my personal experience.....Mobil 1 is junk, just cause everyone hypes it, and they spend alot of $$$ of advertising doesn't make it the best. Never tryed the german castrol...but have only heard good things aswell. THanks

so basically what you just said is..... i have XYZ and it kicks ***. i have not used product ABC, i have no results for product ABC, but ABC sucks because i like XYZ sooo much.

is that correct?

[sarcasm]
its good to know people that use such sound logic give tech advice.

Patman, I think others have asked about this, but anyway, have you seen any comparos between the new Cosworth oils and the usual "standards" (i.e.; GC, various Amsoils, Redline, etc.)??

Patman

I have not seen any oil analysis results on that new oil just yet. I don't know anyone who is running it either so I don't expect to see any coming soon either.

lucky

Try Mobil 1 0w-40.Check the specks hths 3.6 VI 187 Cst 14.2 etc etc.Much better than 5w-30.

Where do you come up with this BS? Can you keep your posts in the lounge section only?


I think this deserves one more look.
Great reasoning.




Back on topic.......I've ran nothing but Mobil 1 5w30. Everything looked great at 100,000 miles.

As a quick side note turbine engines do not use oil for the same lubrication purposes that car or other reciprocating engines do. If you were to use the Mobil oil that turbine engines use you would find that shortly after using it not much would be left of your engine.
