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?
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.
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 would not put that stuff in my oil, He is right that stuff is rediculously thick, Watched a buddy put some in his Duramax. You almost have to spoon it out i dont want that stuff firing my injectors off.
I think you mean "Premium Blue"? Its what I run. I've never been much of a fan of Valvoline, but after my dad started running it, I likes how his truck ran so I started too.
Its not the Valvoline Blue or whatever, its the regular 20w40 and its diesel rated, i have a friend that runs it in his cummins. And i've done put it in there so any suggestions on what i should do?
i have been running chevrons delo400 since i bought the truck 5 years ago. truck has 267k on it and is basically stock except for intake and exhaust. do you guys have any opinions on the delo?
Delo, Rotella, Valvoline. I prefer the Valvoline, but if I'm on the road and pull in to get an oil change and they don't have it, I don't mind running one of the other two. With the Delo and Rotella I will just be more likely to change at 3000 miles. I dont think it makes a difference, I just feel that the Valvoline makes my truck run better, so I like to run it as often as possible.
My dad ran Rotella for millions of miles and swore by it. I'm running Delvac in mine now and like it. Going to try the Valvoline blue next because I've run valvoline in everything I've owned since I was 15. Motorcraft Filter seems to be the unanimous favorite for filter.
1. Valvoline oil "Premium Blue" 15w40
2. Motorcraft filter
3. Rev X (where can I get this and what exactly is it and how much do i put in?)
am I correct on this?
