My latest Fill has been M1 0-40 in my 99 F150. I couldn't pass up the deal at Orielys and can't deny the numbers on paper are awesome for this stuff. Has anyone else used this in a 2 valve 4.6 or 5.4 and what was your expierence?

I used an 820S of course
 
So far it runs nice and smooth. I have heard of people running heavier weights in these engine with good results. I was running redline 5-30 before this fillso there shouldnt be much difference RL 5-30 is pretty heavy. I actually think they spec the same
 
My Marauder 4V 4.6L is lovin' the 0W-40 M1... Was going to use it in my two Grand Marquis' but figured since they are not a high performance engine, 5w30 would be fine... My '98 with 43K mi(grandma car) is now running the M1 EP on a 1yr OCI, the '07 with 46K mi will get the same at next change...

Contrary to the popular belief here on BITOG, you can run about anything in a Ford mod motor and not have a issue... I ran 10W-40 in a '93 till I sold it to a friend at 155K mi... Not sure what he's using but it has around 175K mi, still runs like new...

I used M1 10-30 in my 96 Merc GM 4.6 and did 10K OCIs for the 218K until I sold it. Still ran great with a very clean engine. So 10K is easy with these engines.
 
unless you are using them for Police Interceptor duty, I would say change it out at the factory specs... --or looking at the cumulative mileage on these vehiclesI'd maybe once/year is a better answer

Contrary to the popular belief here on BITOG, I would tend agree and on more than just the mod motors.
 
Def don't want to use a heavy weight in a high revving (7K++) mod motor. I'm sure most anything fine is for the standard pass car.

M1 0w40 is a very light 40-weight and quite similar to a heavy 0w30 like GC.

IIRC, a heavy 30 weight is what is recommended in decently built 4.6L.

Ford spec's 5w50 for the BOSS 302, which will spin to 8K.

Yeah, that's a much newer engine, my bad. John Mihovetz knows more about performance Modular engines than anyone in the world, and has noted several cases of engines that are met to rev high, not rev because the oil was too thick and the hydraulically controlled valvetrain would not work correctly

The BOSS 302 is still a Modular engine sir. The 30-weight recommendation (for the 4.6L) comes from one of the guys that helped design and test the engine for Ford.

The 5.4L in the Ford GT and GT500 (both standard Modular engines) also spec 5w50.

I'm not say run 20-glue-w-60 in them, but certainly a light 40-weight like M1 0w40 isn't going to hurt.
 
Im thinking unless prices go haywire i'll keep using the 0-40. I dont beat on it. I have a coal roller if I want to go fast. Nice thing is you can get it onsale often for 5 bux a Qt

When Mihovetz says "high-rpm", he is talking HIGH-RPM. His race car sees 9500-9700 rpm.
