If we keep adding to this thread, we'll all go old school and run straight 30 in the summer, then switch to straight 10W in the winter. When was the last time anybody saw a straight W-grade on the shelf?

My local NAPA has 30HD PYB, GTX, Delo, and Napa. Of course it is independent and is sort of auto/farm oriented.

IMO, yes. No difference in starting or running. But I did not do a UOA, and my tow vehicles are just that, they tow. When they aren't hooked to the travel trailer, they sit. I drive about 3000 miles a year, from March to October, then it sets all winter. So I cannot tell you if the 30 weight would have worked at or below freezing. But 40 and above, no change in the truck's behavior.

That sounds like ideal conditions for using a straight grade.


And thanks for the links Shannow. You are certainly an asset to this forum and us less informed members.

I don't even see any on my Imperial Oil sell sheets. Heck, they don't even sell a Mobil conventional 10w-40 or 20w-50 up here any longer, and all their monogrades are SAE 30 and SAE 40 HDEOs and two cycle diesel oils.

Would anyone here actually try a fill of monograde in an application where it's tolerated? Just for kicks.

I imagine my tractor engine Jeep would thrive on it. Seriously considering it for fun but I have some timing problems. I'd only consider it during summer and for any kind of telling results it would be better for it to be a second run UOA to get a real look at how it did. If I was due for an OCI now it would work, but I'm not. frown

Another reason why I don't usually run synthetics, you just have to wait to darn long to try something new!

I have posted the following twice:

I have:

1) Mixed 30 with 10-30 in varying amounts
2) Ran straight 30
3) Even ran straight 40 (Im in TX summer and oil was almost free)



Even the 40 did fine in my 97 Chevy pickup.

People are STRESSING over nothing, viscosity wise.

I'm going to put 0W-16 when it comes out, in my corvette for the same reason.

5.7 litre hemi. With mds. I've already experimented with 40 grade oils in it and they slow down mds engagement by .025 of a second or so,so those folks who believe that you gotta run a 20 grade or the mds won't work take note that it's not true.

Surprisingly enough if you get on the throttle before the oil reaches 140f the ecu throws an oil too thick code.
I've got 5w-20 ultra in it right now. 8000 miles on the oil and I guess due to oxidative thickening it set a cel a few days ago when I got heavy into the pedal.

I've seen a 20W...somewhere in the not too distant past, now I'm wracking my brain for where exactly I saw it...it stood out

So you think it would be alright in the summer on a monograde? I'm seriously very curious.

I do because I've done it before many years ago but I was very oil ignorant then and ran it into winter. Starts were pretty rough ha ha. I've been looking around and PYB HD30 is fairly available. So is Rotella. I also looked at the Castrol site and they say in regard to their HD 30 "for ambient temps over 40 degrees". So they seem to think HD30 is fine as long as it's 40 or above.

I am still 3-4k away from my next OCI, it will be summer then, I am torn between another fill of 10w40 PYB or a run of HD30 PYB. But I would rather have a prior run of PYB before I run the HD30 as a UOA would be more reflective of actual performance. But then I'd be getting into fall with HD30 which I don't really want to do. But a single run would not be worthless either.

Like you I am very intrigued by the higher HTHS and the stellar shear resistance.
