10w-30 for the 6.0

[JBakerFX4]

Well I've been running 5w-40 Shell rotella syn for the past few K and it seems to be doing good, but I'm interested in how the 10-30 motorcraft does in our engines? any issues long term? I know they do not recomend it for trailer towing and extreme use; heat etc. One reason I'm interested in it, is b/c it's called out for in the owner's manual and I don't ever tow, and 99.999% it's just me driving around by myself or with 2 folks in the truck and maybe a rocking chair in the back or mountain bikes. so the truck is never really loaded. so I'm interested in the 30wt MPG savings. and I've heard alot of rumors that dealers are recomending it year round... opinions on going 10-30? I understand you can't tow, or haul heavy stuff etc. but for normal day to day soccer mom stuff... i'm looking at it as a option. and I'm all ontop of Oil changes.

Motorcraft 10-30 is not diesel rated so it does noit have the additives to fight soot as the 5-40 or 15-40. Amsoil does have a 5-30 diesel oil thats is awesome.

Wow i didn't even know they had it. I figured you we taqlking about reular api 10-30. Give it a shot

IMHO-- you're taking a serious chance running 10W30 in Florida considering the shear down characteristics of a 6.0 engine. At MINIMUM you should run 5W or 15W40. It's your $10K+ engine. Let us know how it works out.

How does the 5W30 run in any of the PSDs? That 30 hot weight sounds scary, even though it is only 10 less than 40.

[JBakerFX4]

well the funny thing is, in the owner's manual they recomend 10-30 OVER the 5w-40... go figure.

[Lord Tauk]

That's because Ford didn't have their own 5W-40 to sell when that manual was printed!
