hey guys i was wonderin wat u guys use for performance motor oil...i was thinkin royal purple but wat do u guys recommend???

 

Lots of info here: http://theoildrop.server101.com/cgi/ultimatebb.cgi Search around over there.

 

royal purple is good stuff, put it in my 96 z28 helps it run a little coller and feels a little more responsive. also helps quiet valvetrain down a little.

 

All I use is Mobil 1 non-synthetic at the moment. That will probably change when the 383 is in.

 

Used it in my 95, loved it. Will do the same with the 93 next oil change.

 

www.bobistheoilguy.com is a good site also.

 

I use Royal Purple in my Z. I think it works really well. They did a fluids swap on Horsepower TV with it in an LS1- engine, tranny, and rear end. They got a 10rwhp gain just from changing the fluids. I don't know if I got that, but earlier this year I changed the tranny and rear end fluids in my Camaro with the Royal Purple stuff, already been using it for the engine, and I certainly have no complaints. It's pretty expensive, $6 a quart, but I'd say it's worth it.

 

Whaddyado drink this stuff---imho, orl is orl and today's lubricants should do the trick on just about anything you've got...on the other hand, if you believe that one is far superior to another, god bless ya. JMHO

 

RedLine is another very good brand, arguably the best in synthetic oils. I use it in my Jeep and it makes a difference.

 

Some synthetics like Mobil 1 are not true synthetics. They are based on stock [dino] oil. Royal Purple and RedLine are 100% synthetic -- which means that they can handle a lot more stress before the molecules in the oil start to break up, have a much higher heat tolerance, etc, etc, etc.

 

mobil one is a fully snythetic oil check out there website at mobilone.com . They do make a blend but thier other stuff is full synthetic

 

If it was my car I would put in some good quality dino oil--10w-40 along with a good filter and change it regularly. The higher the miles the more the wear--the more the wear the sloppier movings parts get. So in order to keep up the oil pressure, lessen the rocker noise and prolong the engine, I'd steer clear of light weight synthetics and have the piece of mind that comes with knowing that the oil you are using is not going to be the culprit for engine failure.

Yes, but it's still based on stock oil. That is why it's about $4-5/qt and the others are $7-8/qt...

 

Oh c'mon guys. You can "feel" a difference in the way your car performs by switching oil brands? I can see how one might notice a change going from a very low to a very high viscosity oil, or vice versa. But otherwise, I sure don't buy it.

I am certain there are signficant differences between oil brands. What I am not sure of is how you find an unbiased source of information that would allow you to determine which oil is "best". Or, for that matter, what constitutes a better oil. Wear, horsepower, intervals between changes, what? Dyno testing does reveal that thinner (lower viscosity) oils make more power. And even within the same viscosity rating, there are small differences in power between brands. And at the same viscosity, synthetics make a small amount of power over dino juice. But we are talking about quite small differences.

I don't use synthetic in either my race car or street cars and never had a problem I could attribute to oil. That's in 40y of working on, driviing, and racing on a variety of wide variety of motor vehicles (karts, drag racing, road racing, motorcycles). I could see the logic of extended change intervals and synthetic. But they way most people use them (frequent changes) really makes no sense.
