changing my gear oil in the rear and wondering which i shouls order off 5.0 resto?

Royal Purple is synthetic AFAIK (I dont know that they have a dino version).

If you are ordering from LRS anyhow, why not. I would get it where ever is cheapest.

Good luck.

I would go down to the parts store and get some name brand petroleum in an effort to save $10/quart on oil you'll never have to change again anyway, but thats just me.

65SC, that is the reason I would use the synthetic. You dump it in and leave it for a while. The price difference from dino to name brand synthetic around here is about 5 bucks/qt.

Worth every penny if you ask me (which you didnt. ). To each his own.

i agree 100000%

i have been using synthetic in all my vehicles since 1992 or so.

when i change my engine oil after 4-5k miles it's still almost gold, and no where near the color of conv. oil after only 3000 miles., the mpg increase is just a bonus.

royal purple, and amsoil are the best imo....but i use mobil1 for my engine
royal purple is about $7 /QT mob8il 1 is $5 QT

i went to every store by me and they had jack so i picked up valvoline durablend (synthetic blend) 85w-140 this stuff any good?

 

[HISSIN50]

Petey, where are you located? I have used that stuff and IMHO, it was a little thick. Now Redline 85-140 is very viscous and flows very well (better than dino 75-90) in cold temps. But the blend was a bit thicker IMHO.

If running a non-full-synthetic, I would run 75/85W-90. You should be able to get M1 full synthetic gear oil (parts stores here at least sell it).

Good luck.

i live in nyc, i was "highly" recommended to change the oil after 2 weeks of when i got my car back to the shop, could i just use the valvoline till i order some good stuff?

If it is not real cold back there in NY right now, it might be alright. If you just had rear end work done, I would not want to run that thicker stuff though. It would be worthwhile to swap it in for 75/85W-90 IMHO and be on the safe side. Then choose a quality synthetic for the change in a couple weeks.

Good luck.

Bump for someone who uses that product.

I use Redline and Friction modifier, and that is about all these days.
