5w30 compared to 0w30
#5
I dont know everything there is to know about oil... personally I think its all from the same plants and animals that are long dead.. with additives and detergents.. but with that said.. I've been using Royal Purple 5W 30 since I bought it.. and I'm probably paying for the yellow blue and green food dye colors added to the same batch of oil that comes from some part of the world that Dinosaurs **** on 95million years ago.
but I like Royal Purple.

Ow does fine for a running engine, hell for cold/dry starts. If it's a dd, probably ok. But why risk it? I would never run it.
I use 5-30 and a bottle of Lucas oil stabilizer in every change. Stuff has a crap-ton of zinc and is super sticky. Don't have to worry about dry starts.

The only reason I wouldn't use 0W is if you're not driving it everyday because 0W is thinner/less viscous at room temperature and does not adhere to surfaces like cylinder walls for very long periods of time. That causes dry starts. That's probably the only reasons manufacturers don't reccomend 0W just yet.

Thanks for all the input. I owned a Scion Tc that took 5w20 and 0w20. I always filled it with 0w20 syn blend that I had at work, and got me a very slight mpg increase and seemed to do better on cold starts. I think I will switch to 0w30 full syn in the winter months here in MI, since this is my daily driver.
