Mistake using Mobil 1 0W30 with temps warming up?

[Blue_Goose]

I picked up a 5 qt jug tonight at Walmart...not quite sure if I want to put it in with warmer weather coming.....Ecotec 2.2 with 28K on it


Better off sticking with a 5W30 like PP or QS horsepower? Is 0W30 really not a good fit for warmer temps? (PP in the sump now with almost 7500 on it)

Pros or cons if I decide to use the green capped 0W30??

Q: Are both equivalent to, or fall within, the 30 weight range in viscosity at 100C/212F?

A: Yes.

Q: would there be any reason to not use one or the other just based on ambient temp, especially when factoring the upper spec'd viscosity @ operating temp?

A: No.

I would be concerned with 0W-20 for year round use, but not 0W-30. I've used the latter viscosity continuously since January 2007 without problem.

If you are worried about the oil being too thin, the Mobil1 0w-30 is going to be thicker than PP 5w-30 at any temp.

Maybe he was confusing the 0W30 with the 30W0?

I certainly can't imagine why if the engine is designed for it. I've used M1 0W20 SL in the same Accord since I bought it new in 2004. No ticking, no consumption with 7500 OCI's, and 36 MPG on the highway with the A/C on. South Texas is not known for it's mild temps either. Why would using a proven viscosity (regardless of brand) make you concerned?

It is the HHR now...I'll post a UOA in a few months

I live in Phoenix, AZ and switched to using 0w30 year around. Have Mobil 1 in there right now but plan on switching to GC next OCI.

Goose,

No problem using 0W-30 year round. I use Castrol Syntec 0W-30 in my '04 Sienna all year. And the temps here can be over 100F and hotter down at the road level in the summer.

Cheers!

M1 0w-30 is a perfect choice.

Mobil 1 0W-30 will work great in any weather including very hot weather as long as your car calls for a 30 weight oil. However, I wouldn't call these numbers facts either, they are calculated estimates that are most likely inaccurate at the lower temps.

 

[Blue_Goose]

Engine hasn't blown up in 120 miles so I guess it will be ok....now whether my mpg will go up as claimed...hmmmmmmmmmmmmm...not really a fair time to check that out though as the winter blends are on their way out up here and the better mpg summer blends will be in stations soon

Here is a little more info on the viscosity calculator:

It is a frequently encountered task for a tribologist to calculate viscosity at a specific temperature or viscosity index. It will be nice to have a computer program to do the work, especially when VI is involved. This program can be used to estimate viscosity or viscosity index for liquid petroleum products.

The ASTM D341-93 is used for viscosity-temperature relation calculations. The VI calculations follow the method described in the Appendix X2 of ASTM D2270-93 and use Table X2.2.


The actual viscosity results of the off the shelf oil probably vary more from the spec than the calculations.
