I'm trying to come up with a middleish weight 30 weight and have a 5qt jug of M1 0w-40 FS (GTL version).

I'm thinking about buying 3 quarts of PPPP 0w-20 (GTL version D1G1 which is high calcium no mag like M1).

3 quarts of each making a 6 qt blend, what's your thoughts? Both are GTL, both have high calcium, no mag, etc.

IMO it's not good to mix chemistries of oils. Not because impending harm will come to your engine but you might not get the same performance characteristics out of the blend that you would with one oil. You would be better off looking at the data sheets to find the middle weight in an oil and go with that only.

From some of the mixes I've seen around here, yours actually makes sense with similar chemistry. Such blending in New England weather poses less risk in the spring-fall since you aren't worried so much on the oil mix works at the low viscosity end of the spectrum.

If the car weren't anything special I'd be mixing those same oils if I wanted to use up the M1. Ideally, an OCI less than what either oil can normally do.

LGX (in trucks) LGZ (in cars) 3.6 calls for 5w-30 normally, probably fine to run straight 0w-40 m1 in it, just not sure how much it would affect mileage..

You need 6 quarts ~ use the whole jug and one quart ... quarts are expensive unless grabbed on clearance …
That is not a thicker 40 to start with … I run it in our Cruze now …

Here you go

http://papers.sae.org/932831/

I personally think its' likely that most of us don't push the extremes of the "W" rating that we hear of relatively few.

The linked SAE papers, the oils gelled at comparatively "normal" temperatures due to VII/PPD interaction between the factory fill residual and the service fill.

I wouldn’t have the first thought about using it in anything ‘round here. Might cut the OCI interval a little short tho...

Someone here once opined that if your heart meds clash, you die. If your oil add packs clash, you wind up with 10 more ppm Fe in your UOA...

Blend on brother, blend on!

Wouldn't it make sense to use it up in an oil change soon as it's a 0w? Why wait until summer to do the 0w-40 run?
