Hi, just a quick question if I may, just wondering how many of you are using 5w30 whatever instead of 5w20 whatever, and if so, anything better or worse to say about using the 5w30. Not to many uoas on this subject, thanks for your responce.

In my 95 Vic I have been running 15w40 Syntec Blend to
control oil consumption (Mod motors up to 95 have lousy
valve stem seals). If I didn't have oil consumption
problems then I would run 5w30 in her with no hesitation
because that would mean I buy only 1 oil weight for my car
and truck. Ford spec'd 5w30 for the fist mod motors then
later back spec'd 5w20 for all mod motors, so IMO 5w30 is
OK for mod motors. I would be willing to wager that there
would be little difference in wear shown on a uoa between
5w20 and 5w30 of the same brand considering that many 5w30
's shear down to near 5w20 in use. So IMO using 5w30 is ok
for any mod motor.

A lot of people run 5w-30 and a lot run 5w-20. The debate between the two rages on. I prefer 5w-20. In the grande scheme, use whichever you feel best with.
I've only ran 5 and 10w30 in my 4.6 in my t-bird, even though its backspec'd for 20 weight.
same with my dad's 98 f150

I run GC 0W-30 in my 5.4,another family member runs Amsoil S2000 0W-30 in the 4.6 also with no problems.Both use these oils year round in New England.Winter starting is a breeze with no engine noise.
I tried 5w20 in my old 93 Crown Vic that had 200000 odd miles. Engine seemed to like it but the valve stem seals didn't.
We had a mod motor in the shop (V-10) that had it's valves stem seals done. When the main and rod bearings were pulled they were like new. The crosshatch in the cylinder walls was still perfectly clear.
That was at 185,000 or so on 5W-20 and 5W-30 depending on if we changed the oil or some other shop.
It will go on for some time to come.

I have 210,000 on my 4.6 liter, 5w30, never any problems.
Here in South Florida I have been running M1 10-30 with stellar results on my 98 F150. UOA were even better the time I added a quart of 15-50 to the mix, as I was short a quart. I now have 180K and doing fine. Most likely the engine will last double that. A borescope down the spark plug holes shows crosshatch! This is one tough, smooth running, long lasting engine. Been through a bunch of other components though.
My coworker has 4.6L engines in fleet service with one example that made it to almost 900K on M1 10-30. Hard to argue with that, considering that similar fleet engines on dino failed much earlier, with local police/taxi cars making it about 200-250.

Look at all the Police and Taxi agencies that use bulk 5w20.
I have a 99 V10 and have been using 5w-30 until this month. I finally tried 5w-20. 85k miles with no problems.
I've yet to do my first UOA, but that's coming up soon on the 5w-20.

I've run both 5w20 and 5w30 in two 4.6L V8's in a '97 F150 and a '99 F150. Honestly, no discernable mileage difference between the 5w20 and 5w30 oils, perhaps slightly more consumption on the 5w20, but nothing to complain about.
I sold the '97 F150 running 5w20 at the time with 163,000 miles on her and I still se it running around. My '99 has 151,000 on her and no issues.

i vary between the two, as does my dealer. after the spring change of 5W-20 Q-torque 4x4 oil, i'm going back to MC 5W-20.
5w20 motorcraft in a 98 f150 4.6L with 80k. Uses about 1/4 quart every 5k miles.
Great results.
10w30 PP in a 99 mustang gt engine that is vortech supercharged.
Again great results.

@002 Lincoln Intech 4.6, MC 5w20 for 56000 miles, but iam going to try PP5w30 on the next change and go 6 monthe/5000 miles. I always changed the MC at 3000/ 3 months. Great oil samples.
