This spring I'm thinking about trying Penzoil Ultra 10-30. Had Penzoil Platinum 10-30 last year. The years before that it was mobil 1 10-30. I switch between the mobil 1 filter and the purolator pure 1 filter.

Car only comes out from months of april to sept. so the oil just gets changed once a year in the spring time. In those six months it only logs about 5000 miles.

Only bad experience I've had with a motor oil is Royal Purple. It was the only oil to make my engine sound noisy. I've heard some people swear by it but I didn't like it.

 

I'm running mobil 1 5w-30 and change my oil every 3000 miles. I just did a cam swap and my engine was clean as could be on the inside looked like a 40-50,000 mile motor but really it has 169,000 miles. Lol

 

i voted Castrol syntec, even though i use Castrol edge. i use to run Mobil1 10-30 but after i switched to Castrol edge, it made the internals a lot quieter. and its cheaper than mobil

 

I've been using mobil 1 but I'll be switching over to pennzoil platinum this summer since mobil 1 stopped being a class VI synthetic oil. Haven't chosen a new brand of filter to go with it just yet.

 

I don't ever change the oil. I just stick with the assembly line fill. It's been fine for 13 years. LS1s will run forever, with or without oil. Sometimes I can even get it to run without any gas in the tank. What a great engine.

 

I use almost anything on sale, and my 98 is at 222,000.

 

The only oil i ever run is castrol. My old 00' Z28 i ran regular castrol GTX 10W-30 and never had any problems. Now with my current 02 Z i run castrol syntec 5W-30 and no problems at all. No oil consumption issues, loud valvetrain or anything.

 

my SS came with castrol and i used that for awhile. now i use m1.

 

Mobil 1 5w 30 every time. But then again I only really change my oil once in the spring and once in the fall since i don't drive all that much

 

Synthetic:
Motul 8100
Amsoil
Lubro-Moly

Oil Filter:
Amsoil EA is rated the best
Canton is #2
Wix is a very good filter too (NAPA)

And Lucas is a good additive for the oil

Good info on oil filters with cut open cans

I also like Red Line fluids for the Trans and Rear, and Transfer Case when I had my 3000GT VR4

I use Mobil 1 synthetic 5w-30 in both my cars.

 

I had RP in my SS then switched to Amsoil. ***** expensive though

 

Mobil 1 0w40, thinking seriously about switching to Shaeffer Oil tho...

 

I doubt it since it is $35 a QT , but has any of you use SynLube Lube-4-Life motor lubricant (it's not an oil) or the MicroGlass Motor Oil Filter? It bad *** ****!

I'm thinking about giving it a try in my 450 stroker once I get it broke in, but at $250 for the oil change, I'm gonna want to then myself, but then again, it's good for 50,000+ miles

BTW - I was joking if you didn't catch on

Valvoline syn 10-w30 it is the only oil with a motor mileage guaranty, now that is standing behind your product.
The reason, Valvoline refuses th pay GM a royalty the qualify as a long drain replacement oil for GM's new Dexos world use, syn blend, long drain oil. So Valvoline just warr. the motor themselves.

 

Penzoil PP, 10-30.

 

havent changed the oil in the camaro yet. will soon. but in the 8 sec turbo s10 and 10 sec nos blazer i run castrol gtx. simple and damn effective. the nos motor has went 9s for 3 yrs on spray had a 6-71 blower on it and is 13 yrs old. still looks like a new one. it gets a tear down and new bearings every 2 yrs. though. turbo motor i just pulled looked brand new inside. couldent tell it had ben ran on the bearings, the cyl were moving a lil but no pistons scuffing. i guess the stock block did its job running 8s for 3 yrs. now i got a dart block it will get castrol. gtx as well. i change oil about every 2 events. so about every 4 miles. lol on e85

 

oh and i run fram hp filters. seems everyone is scared of them too.

 

royal purple 5w30
