Rotella VS Valvoline

[hvprohop23]

So ever 7.3 i've ever owned i've run nothing but Rotella, but here recently i had a friend recommend trying valvoline. I normally run Rotella 15w40, but instead i changed my oil yesterday and tryed Valvoline 20w40 with a half gallon of Lucas Oil Stabilizer.

My first impression of the Valvoline is WOW, i love the way the motor feels, soo so much smoother idle and crusing along, seems a bit quieter too, and even starts easier. With Rotella i had the real loud first crank when the truck started, almost sounded like it was startin dry. But with Valvoline its nothing even close, smooth start, smooth idle, smooth everything.

So what im askin is for opinions? Or does anyone think the higher viscosity will hurt the engine?

And while im askin i usually use Fram filters but went with a Motorcraft this time.. Yes i know Motorcraft is the factory Ford equipment, but is it as good or better compared to others?

All help is much appreciated.

The Valvoline was actually about 5 bucks cheaper for the 2.5 gallon jug

Ive been running the Valvoline for months now, and like it. It does make my truck run quieter, and smoother. Then again, 20 days at most and I'm doing another oil change with the miles I put on... I like the Valvoline, if I can find it locally. I usually pick some up at Wal-Mart's out of town since the local one doesn't carry it.

I might have to try it since Im kinda experimenting with oil. The mobil delvac Im running now makes it idle rough and loud, and the truck is burning oil while running it.

Try it and get you a 1 gallon jug of Lucas Oil Stabilizer, its about 40 bucks for a gallon but man it works wonders.

I thought we don't put nothing but oil in our trucks??? Dosen't the lucas foam up from the hpop could have sworn I read this somewhere not to add stuff like this due to hpop pressures.

I'd never heard that, i could see it happenin though cause that stuff is thick is mollasses. I had to mix it with the oil just to get it to go down the funnel

I usually put on 6+K a month. I try to keep it changed around 4,000 miles this time of year, because when it gets cold like this, I just leave my truck running while I work. ND is a cold desolate wasteland. Its nothing for me to be waiting on location to go to work for a day or two, and have no where to stay but my pickup.
