i have a few gallons of rotella 15-40 from my diesel and i hate to see it waisted. can i use it in my 2001 f 150 6 Cy.?

 

how many miles on your 6 banger??

Personally I wouldn't...unless it summer time and then maybe only 1 quart at a time and there is a pile of miles on it (150K plus) and already had a lot of valve clatter. You obviously then be nursing it along unitl a rebuilt engine could be had or the new truck was ready for your drive way.

If this thing runs very good and lower miles...defiantly not. Then I would advertise the left over oil and sell it and at least recoup some funds. some truck driver would defiantly take it off your hands.

 

it amazes me how some people risk screwing up their engine to save a few bucks.

 

I wouldn't. Use it in your lawnmower or something.

Off topic - how come 80% of the people here spell "definitely" "defiantly"........

 

I don't think it'd be a problem, not on a 6 cyl, but on a 4.6 or 5.4, the thinner the oil, the better. Diesel oil is good oil so give it a try.

 

Nope lol.

 

i wouldnt, its too thick.

And to glc for the off topic comment the only reason I can think of is that you try and spell definitely wrong and it will spell check it to defiantly at least that is what happens to me

 

Can you use it? Yes.
Should you use it? No!
Find someone with a diesel that takes that mix and let them have it for 1/2 price

 

When Ford redesigned the Crown Vics in 1992 we had a Chief that swore we would be better off using 20w50 oil instead of the Ford recommended 5w20. Long story short, in 1993 Ford charged right at $4 grand for a new 4.6 engine and installation.

 

would not even risk it.

 

I know, right...

 

no, dont risk it!!

 

When my work truck ('03 5.4) had a head gasket oil leak, our mechanic gave me a few qts. of oil to keep it topped up ... 15-40. When I asked what was up w/ the 15-40, he said "... we have so many different types of vehicles, we pick one wt. of oil and use it in all of them ...". Last time I was in for an oil change (145K), he put in 5-20. When I asked him why the change, he told me they just lost a V10 at very low miles and when they talked to Ford the first question was " ... what oil are you running in it ..." (they'd been using 15-40).

That being said, my work truck has been run for 140K on 15-40 changed at 6K intervals.

 

It also says to put unleaded gasoline in your truck, but go ahead and put diesel in.

 

Personally I run 5-w30 in my truck. I have a friend that had a 4.6L and all he ran it was 15-w40. He bought the truck used in highschool and when he sold it it had a bit over 200K miles on it. ran perfect.
