15/40 wallmart oil ?

My parents were die hard Quakerstate or Penzoil fans so thats where I started out, Penzoil.

My Dodge 400ci gasser would use a quart of oil every 1000miles, even when new. When my usage got too 1qt/500 miles on one change I tried quakerstate. My usage dropped back too 1qt/1000miles. Then my usage went back too normal until Quakerstate was bought out by Penzoil then it went right back too 1qt/500 miles.

When I bought my PSD, I decided on Delo. I also changed to chevron surpreme on my 4cly gasser. I got 5mpg more fuel mileage using Chevron 10w/30 so that was a positive change over using QuakeState. My son also tried Chevron Surpreme and picked-up 4mpg on his Ranger 8cyl Vs what ever the quickie change places were using.

As to cost Vs wear, I think you would only notice time to overhaul vs using a cheap grade oil. I don't know of anyone that ever had a oil failure problem on any oil.

I had a buddy that was a Amsoil die hard. His BIL bought a motorhome at the same time. BIL used what ever was the cheapest. Both rebuilt transmissions at around 50000 miles. Both rigs were approx. the same weight and my buddy babied his driving where his BIL floored the fuel pedal at all times. So why didn't my buddy's MH get more mileage between rebuilds while using Amsoil???

I think it's more important to use the correct weight of oil with frequent changes. Multi-weight oils are great for travling between different temperatures but where you have consistant temps for working engines, I'd use straight weights according to the temps there running in.

On my PSD, Delo 15w40 was to heavy of oil for 5�. It started but sure moaned about it. I'm sure glad I had glow plugs. I can't find Delo 10w30.

But even saving a $1/gal, would you save that much money vs shorting time to overhaul???

I use the walmart UTF oil in my tractors.. no fialures yet.

i had a hyd remote added to my 2002 NH 7610s a while back, dealer had the hyd system apart and i asked them to replace orings and check pump and relief while they had it.. ( just to make sure the walmart oil wasn't killing it ).. dealer said it looked brand new ...

I change the oil and the filter at LEAST by manufacture rec's.. or better. I think tomtex may just be a little mad cuz he sponsors nascar commercials and advertising and such! (wink)

Honestly havn't used the supertech oils in the crankcases except as flush oils due to the extreme low cost. Any time i get a new-to-me tractor i change the oil with superthech and slap a fram fitler inthere,.. run it around for a few days then drain it, and go in with valvolene or napa fleet diesel and an oem or napa filter, depending on the application.

Again.. I DO use the UTF and gear oils though. No hyd failures on any of my antiques yet... no drivelines have droppe dout in middle of the road either.. no discernable metal in drainings or on plug magnets.. etc..

I've had ABSOLUTELY no problems with any of the engines I've used it in. I recently had the oil pan off of one of the high-mileage engines 'cause the kid smacked a rock, and it was just as clean in there as any other engine I've ever been into.

However, I noticed that the engines smoke MORE with this oil, and very little with say, pennzoil.
