As I've said a few times, when I first got my Jag the Jag forums recommended 20W50. Since reading and posting on here I've discovered that I don't really necessarily need that thick an oil. So, just out of curiosity, what would take a ??W50 oil these days?
What applications does a ??W50 have now?

Only very old cars like 1970s and earlier British stuff.
There are a couple of current odd ball applications for 5W-50.
The 20W-50 grade is obsolete.

Doesn't one of the new Mustang versions (Boss 302) call for it?
Some motorcycles?
High performance cars that can run high oil temps when driven as intended (i.e. not bumbling around at the speed limit).
I know the Lexus LFA and McLaren Mercedes SLR spec Mobil 1 5w-50, and several hot Mustangs and the Ford GT have specced 5w-50s as well.

Yes the Ford GT and Cobra I think but the spec' GP III Motorcraft 5W-50 shears about 25% the second you fire it up.
A quality GP IV oil like M1 0W-40 probabily would deliver the required operational viscosity without all the initial shearing.

Some tractors do.
Mobil 1 also has a 15w-50 on the market, still in high demand, supposedily available by this summer in 5 quart jugs.
I guess the drag racers and Motorcycle entusiasts use this oil.
Since, all Mobil 1 oils are compatable with each another, this oil should pose no problem with mixing and blending. This heavy full synthetic oil, can be mixed with other Mobil 1 oils, synthetic or dino oils.

Yeah, I have an orphan quart of that stuff I bought based on those 20W50 recommendations. Anybody want it

I believe Mobil 1 5w50 and Castrol Syntec 5w50 are still VW502/505 certified.
I was actually looking for M1 0W40 when I got the 15W50. They had lots of it and no 0W40 - now I guess I know why
M1 5W-50 meets the Porsche A40 engine approval.

Got a 4-stroke lawn mower?
I've been using the 20 year old dino 20W-50 I still have in my stash in mine. It will still be a couple of years before it's gone.
Or you could buy nine quarts of Toyota 0W-20 to blend it with.
The result would be a a high VI 5w30.
