I have a 2001 F250 Lariat Crew Cab with the 6.8 V10. It has 60K original miles on it and it's been well taken care of. I changed the oil today at just a hair under 3000 miles and noticed it used a shade less than a quart since the last change. It's only the second oil change I've done since I bought the truck (it had 54K when purchased). It seems like I'd read in the past that these motors commonly use a little bit so maybe that's OK. Just wanted to double check with those in the know. I use Valvoline 5W20 conventional oil and Motorcraft filter. What do you guys think? Worry or no?

Also, since I'm posting just another real quick question. I have BFG All-Terrain 265/75R16's all the way around. What's a good tire pressure? Normal everyday driving. Rarely do I haul anything (I actually haven't hauled anything since I bought the truck other than my garbage to the dump.). I'm currently running 50 PSI front and 57 PSI rear.

Your thoughts on both these questions would be greatly appreciated.
Thanks guys and Happy New Year!

 

There was a change in oil weight sometime ago that stated that the V10 can use 5w30 to compensate somewhat the oil usage.
Go lower in the PSI if you want a comfy ride something like 40 front 45 back . the suggested psi on the door is for when your hauling or towing

 

My 05' Excursion V10 used about 1/2 quart between my 5k mile oil changes and I used Motorcraft Synthetic Blend 5W-30 and Motorcraft filter.

 

Just what freaky said!

 

Agreed with others posting above.

I reduced my oil consumption by switching to straight 30, but I still used 2qts in 4,000miles. (Used to be 1qt every 1,000 when running 5w20)

i do have a small oil leak at the filter/coolant adapter thing, but it's very very small. Just a couple drops when parked overnight.

 

I had used MC 5W-20 synthetic blend and switched to Mobil full synthetic 5W-20 and noticed the full synthetic consumes more oil between changes.

 

When unloaded try 65-70psi up front an 55-60psi in the rear and see how that goes. I always keep less in the rear when unloaded as the front has more weight than the rear. When loaded I bump up the pressures in the rear. Less pressure in the rear helps keep it from jumping as much and with traction.

My dads V10 always used at least 1 quart in 3k miles with his normal driving. On a long trip of over 1k miles there is no noticeable consumption. His normal driving is short trips so I figured that was the reason for consumption. Mine maybe uses 1/2 a quart in 3k miles at most. Try some 5w30, conventional or synthetic. Put in 6 1/4-6 1/2 quarts when you do the oil change so you have a cushion for consumption.

 

Thanks for the replies everyone. I'll switch to 5W30 at the next oil change and see how that does. As far as tire pressure goes, there seems to be some variation in what folks like to run and nothing that's really standard. I think I'll go with 50 PSI all the way around, see how it feels and adjust from there. If I haul something, I'd obviously bump that up. Thanks again folks!!

 

I run 55 front/60 rear when unloaded, that smooths the ride as much as possible without feeling like the sidewalls will fold under when cornering. But that depends on the specific tires you are running. Some have stiffer sidewalls and can stand less air pressure, some flex too much if you drop the air pressure much at all. Personal preference.

 

Everyone is a little different but I still run the 5-20 in my 1999 CC LB. Dino oil. It'll burn 1 qt in 3-4k miles. Been doing it for 17 years (just rolled 200k).


Tires I've had 315's x75 16 for about 14 years. Current are geolanders which I really like over the KO's I had for the last 3 sets. I think I'm around 50-f 45 rear. Whenever I ran more in the rear the center of the KO's would wear before the outer tread because I was empty most of the time. The fronts wear flat with the weight on them all the time

 

what is KO?

 

B.F. Goodrich all terrain radials.
BFGoodrich All-Terrain T/A KO

 

ok great so what does KO stand for?

And secondly, how were the rest of us supposed to know that?

 

From the provided link.
"The All-Terrain T/A KO ("KO" for Key benefit On- and Off-road) is BFGoodrich's On-/Off-Road All-Terrain light truck tire developed to meet the needs of pickup truck and sport utility vehicle drivers who want confidence and control on and off the road. The All-Terrain T/A KO was designed to deliver go-anywhere traction along with outstanding durability and great wear."
The newer version is the KO2.


As far as how the rest of us are supposed to know, beats me but I've never owned them and I knew somehow.

 

Oops, sorry about the KO. Pretty popular tire around here. They are Knock Outs!!


I had gotten REAL good mileage out of the BFG's KO's but the geolanders (yokohama) are really a big street tire which is want I wanted. The BFG were terrible in the mud anyway with the closed type tread. And I shopped around at different Discount Tire of Texas stores on the web(some tires have different prices at different stores) and the store closer matched another store. $200 each(plus, plus, plus).
