What kind and brand of engine oil should be used to get true horsepower from your engine.
I have used castrol synthetic and edge brand. The engine does perform well when using full synthetic oil. Just want to know what the other members have been using to get the best outcome. Plus it would be nice if the replies give zero to sixty times.
FOR INSTANCE MY 1998 MAXIMA GXE RESULTS ARE AS FALLOWING
Castrol full synthetic 9.5
valvoline high mileage 14.4
mobile one 11.4

And a combination of mobile one with liquid molly and marvel mystery the best I got was 8.2.

 

lol oil has nothing to do with horsepower. synthetic is best, if youre burning oil run 10w-30. if youre not burning oil, run 5w-30. easy as that

 

Its been a while since I laughed like that.


No disrespect to the OP intended.


That is all.

 

Mobil 1 0W-40 with pure one filter. Walmart has the oil for $25 a jug(5qts) but if you go to a parts store it'll be $50 for the oil. Great cold start lubrication and GT-R rated on the back. Curious to see your results.

 

lol

 

No No ... it's not oil that improves E.T.s, it's octane!

 

This is driver, track and atmospheric conditions, not your engine oil.
And those numbers being so far apart really point to the driver if anything...

 

0w-40 is for brand new cars that have tight azz bearing clearances, on a nearly 20 year old car youre gonna burn oil like a **** with 0w-40

 

14 sec 0-60? god I would kill myself

 

You won't have to ... merging into traffic will do that for you.

 

Why would he burn oil with 0-40? That's a zero weight oil with friction modifiers to make it act like a 40 weight when it's hot. 40 weight is to heavy, the zero will give a nice easy start up when it's really cold outside.

A 0-15 or 0-20 might be on the light side, not 0-40' that's actually to heavy at operating temps.

Also the bigger the spread, the more modifiers. Also not a good thing.

 

Although I totally agree with 99% of these statements, I have to disagree one: that a 0W-40 is too heavy at operating temps.

I've run either a synthetic 10W-40 or a synthetic 5W-40 in my 137,000 mi. VQ30 for years ... it loves it. And my UOA proves it.

But ... I do live in FL.

 

How was your oil analysis with 5W30/10W30 compared with the /W40 variants? What differences stood out?

Also, 137,000 miles on a 15 year old car comes out to 9,133 miles/year. Not your daily driver I assume?

 

I never had a UOA done when using the W-30s ... just the 5W-40.

Although the car runs very well and very quite on the W-40 stuff, I wanted to make sure it was truly happy and not just keeping it's mouth shut.

I had the opportunity to have one run so I did.

I don't have any other analyses from my motor to compare it to, just the statistical norms and acceptables.

Actually it is but I still only have to put about 125 mi./week to go to and from the office.

 

For oil the castrol edge syntec that's made in Germany which is 0w30 is better than the Mobil 1 0w40 because its a thicker 30 weight and it does not shear as fast as the Mobil 1 0w40 and it lasts longer. The Mobil 1 becomes a thin 0w30 after a while where the castrol stays a30 weight and has better shear stability. This is one of the best oils on the market available.
