talk is cheap, bring real world results to the table

 

ok but neither of our engine mileages matches, and nobody else in their right mind is gonna run recycled oil in their LS1 to do an oil analysis.

 

Um...look around hilljack. There's plenty of topics all over the internet involving real world tests of synth vs dino.

Maybe your car is faster since you put the Ford Crown Victoria police interceptor emblem on

 

I take offense to that. I didnt do anything to you.

Are you just jealous becuase my stock car is faster than your modded car that you paid AT LEAST twice as much for?

btw nice site do you even own an F body?

 

c'mon now fellas. That's enough. Everyone go drive their LS1 around and blow some steam off

 

You gotta heads up anytime

 

Ok, serious question for a first time oil changer on my 99 LS1(daily driver), and it's starting to get colder here(60's now and eventually 30's). I won't be changing the oil again until mid February or March, so what do you oil guru's recommend? Is Royal Purple better than Mobil 1?, What should I use 5W-30 or 10W-30 or any other? Any opinions are appreciated.

 

Run German Castrol 0W30. It's been proven through oil analysis that Mobil 1 and Royal purple are too thin for our engines. Reguardless of outside temp, the engine will be operating hot most of the time(30 degrees isnt that cold anyways). The 0W30 will meet all your needs. Make sure to buy the one that says Made in Germany on the back..it should have a green or gold label in the front. It will also say approved for Porsche somewhere on the back of the bottle.

 

OK, thanks I will look for that when i go to the store in a little bit, one more thing what oil filter do you recommend?

 

I run Mobil One filters on my car. They are like 12 bucks at Autozone. The Autozone by me also carries the Castrol. And the great part is it's cheaper than the Mobil 1 oil . (Remember make sure you get the GERMAN version of Castrol, not the regular one.) Look around the forum for pics of the bottle...do a search.

(It seems people were having better luck with the green version. Now it's reformulated and it's gold. Either way it's better than the 2 oils discussed in this thread. You can also try Amsoil if you can find it around you. Castrol should be fine though)

 

Thanks a lot man, I'm sure one of the parts stores around here will have it.

 

Well I went to Advance Auto Parts, Napa, and Carquest and asked them if they carried German Castrol, not one person working in the stores has ever heard of it. So I guess I'll have to call around, is there an online site that keeps it in stock?

 

amsoil 5w30

 

The people working there probably dont know the difference. Just go check for yourself..or like rdeterman said, you can try to find amsoil. Good luck

 

Mobil 1 5w30 in the 'bird
Mobil 5000 in the truck

 

Amsoil's easy enough to find here on the boards... just send me a PM, I'm an independent dealer for Amsoil.

 

well i get free oil changes because im a supervisor at jiffy lube. ive been using mobil 1 5w30 and it seams fine. i did use teh cartrol syntec 5w30 once and i changed it back to mobil 1 with in 500 miles it just made to much noise (piston slap) we do have some 0w40 mobil 1 im gonna try that next time, maby that 15w50 mobil 1. i dunno

 

10W-30 Mobile One

 

as far as M1 goes whats better year round in a warmer climate like Texas, 5W-30, 10W-30, or something else? I've been using Mobil 1 10W-30. I'd like to stay with the M1.

 

Mobil 1 5w30.
