Anybody use 0w30. Living in Mi I figure it would probably be great to use in the winter. Opinions, thoughts and experiences?

 

I do.

I run it year round. you can too.

 

why not just stick with the 5w30 the manual says, it works perfectly fine summer and winter

 

Castrol Edge 0w-30 is a good one to use.

Never had a reason to switch from M1 5w-30 tho

 

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.

 

I'm worried about my timing chain rattle. Would it be rattling because I use 10/40? I just change everything back in January. Gears chains guides and tensioner.

 

Thicker oil should reduce rattle unless it's blown the o-ring in the tensioner. Check your guides first. Ten te a new tensioner.

 

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.

 

0w30 Mobil 1 or similar is perfectly fine.

Should even see a little better gas mileage from it.

 

Have you read te fine print on the fuel mileage claims on the 0W jugs...

 

No but I'm sure it's a marketing gimmick.

 

You would only see gas mileage increases when the at temp weight is less. The motor works less at higher RPMs to push oil.

I run Joe Gibbs 5w-40

 

It's something along the lines of "saves $100 in fuel over the life of the car"

 

Not true. My lady's Mazda recommends 0w20 and it's on the fill cap. With that said, been using amsoil 0w30 for a long time. Sitting at 69XXX, dyno pulls and it's strong.

 

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.
