Okay okay, so opening an out of the box oil discussion when talking about a Ford is a great way to accidentally cripple the forums for a brief period. This is not what i'm hoping this thread will turn into however i am curious if anyone has any better knowledge/experience with this than myself.

Alright, so to prefix this though here's the skinny on my toy. It's a 6.2L raptor with 215k miles. it's a first year truck that isn't particularly valuable compared to first year trucks with low miles, or 13+ trucks with all the updated comfort features. So yes, this experiment very well could cause wear in my 6.2L, but this thing is a play toy, and is no longer in its prime to begin with so here we go;

it gets run hard when i drive it. as in extended high RPM abuse, hard starts/stops, and gets idled like a diesel in the summer, this engine is about as bulletproof as anything, however. With it being at high miles, well broken in, and with summer around the corner, i am considering jumping up from 5w30 (current oil spec for 6.2's) to 5w50 Motorcraft Full synthetic. Now i've read the SVT threads stating that that oil shears pretty hard to a 5w30 basically anyways, so i really can't see where this is going to hurt my 6.2, since after i put that oil in, it's going to be going right back to getting ran hard.

However, i'm no genius, and i'm certainly not the most knowledgeable person on this forum, so here we go. Does anyone have any thoughts on potential risks in this situation? Ford Specs 5w50 in all of its engines that it predicts will get ran hard (from the focus RS to the 5.0 track packs, to the Ford GT) so clearly it thinks that engines that get overworked, and ran hot could use that little bit of extra protection.

just an out of the box thought that i havent been able to find any readings on

P.S - i don't think 5w50 belongs in a raptor that's still under warranty, or not ran hard, and i'm not trying to argue that point

I run 0-40 in my 13 GT500. Have run 5-30 in it in the past. I don't track her though. I don't recall MC 5-50 being regarded as a great oil anyway.

I can't think of any reason I'd run expensive and nothing special MC 5W-50 in that application.

I can. A well worn high performance engine that is driven hard might benefit in the summertime.

That’s just a supposition though.

Why not take a UOA at say, the 5k mark and make a judgement then? If the current oil is hanging OK stand pat. If the wear numbers are a little high, try the thicker oil and retest.

Pretty much solely depends on oil temperature. If you are seeing 250+ then going to the 50 weight might be of benefit.

I would run a good 0/5W-40 in it. Maybe Mobil 1 10W-40 HM. Or T6.....

Doubt it would cause any harm at all... but I'm not convinced there is a real benefit. What type of oil temps do you see?

I haven’t had the truck long enough to have any more knowledge on wear metals in my previous UOA’s other than Blackstone telling me they were a little high and to potentially shorten up the OCI to 4K rather than 5 and see. This was running PP 5w30

Peak temps i've seen are in the 255-260 range but to be fair that was pushing it a bit harder than even i normally do. Highest numbers i usually see are /after/ a spirited run, once the truck is stationery (sitting in traffic etc.)

Why not try a Synthetic High Mileage 5w30? Most HM oils run on the higher side of the viscosity scale and the extra additives won't hurt either. Easier to find as well.


yup

I agree a Euro 0w-40 or 5w-40 or HDEO 5w-40 would be a reasonable, cost effective choice.

The Pennzoil is a thin 30 weight, and at these temps this would be getting quite thin. Personally I would probably use the 10w40 Mobil 1 HM someone mentioned earlier, seems like a good fit for this application.

Sort of. i only feed mine 91+ and the premium prices have barely fell around here. 87 is down to almost $1.40 but premium is still hanging out in the 2.30-2.40 range.

my only worry here is cold flow going up to anything 10wXX - these 6.2's already make a pretty good rattle some of the time on cold starts.

If Blackstone is already flagging the samples as showing too much wear, by all means switch to a beefier grade of oil. Test again after the summer. If you like the numbers,
Consider using a thicker oil into the winter.
