valv maxlife 5w30 ok in 4.6 engine?

[aztec12]

Is it ok to run this oil in my f150 4.6 engine,with 112k on it?it doesn't burn or use any oil i just wanted to try it.
Is valvoline maxlife 5w30 to thick for my engine,couse i read here that high mileage oils run ticker.
So is this 5w30 HM oil as thick as a 10w30 reg oil?
Any 4.6 engine owners here using this oil? tks for your help.

what oil are you using now?
how many miles for your OCI?

Won't HARM a thing. I prefer 5w/0w20 in the ford modulars.

I believe Maxlife is now made in 5w20, but trying to find it on the shelf is another matter.

Maxlife is not as thick as other himi oils like Pennzoil or Castrol.

thank you for saying that! I have more faith in that answer than anything else i've read on this site or the Ford site...
I have Q-power 4x4 full synthetic 5W-20 standing by and then, eventually (takes me a while to get 5k miles) i'm going back to MC blend....

I had to check 3 Walmarts...the one closest to the house stocks VERY few 5W-20's...the other stocks mostly 5W20's.

I would run any 5w30 api sm oil, just due to the mileage.

If you were running 5w20 for a while with no consumption issues, I would recommend that.

What is going on in the Valvoline world? I seen new Valvoline Maxlife semi-synthetic. Is Valvoline finally marketing Maxlife as a semi-syn? Or is a complete new formulation?

 

[MNgopher]

No worries. 5w40 will also run fine with little change in UOA results, just kills the gas mileage.

If you mean Maxlife, it would be the same at 100C. Other brand HM oils are thicker.

Valvoline was keeping their semi-syn Maxlife a secret and was just marketing it as a conventional high mileage oil, but since TallPaul has told the whole world about Maxlife being 12-22% PAO, they decided to go ahead and market it as such.

my oci is usually 3 to 4 k miles and i have used 5w20 and 5w30 conv. oil

 

[Merkava_4]

Are you saying you've tried both already? Which one did you like better?

 

[aztec12]

truth is that i didnt find any difference between the two oil grades.
