I had planned to run 100% synthetic oil in this truck since it is double overhead cam, mainly for durability of oil and faster delivery of oil to the cams.
The 3.6 like I have has had some rocker arm failures from what I read, and this oil is priced as well as any oil out there that is name brand, and it is Chrysler approved, though that doesn't matter much to me, and it supposedly has a good wear additive.
Mainly I'm looking for an oil that will quieten the cold start rattle the V-6 engines have. Don't know if it's timing chains, tensioners, or what. Since Chrysler chose to have a cartridge filter on top of the engine without an anti-drain back valve, I want all the start up protection I can find.
As far as oils, on my old F150 with a 300-6 and my old Ram 2500 with a V-10, I run a 50/50 blend of Delo XLE 10w30 and 15w40. This equals out to 12.5w35..lol
Both run great and use no oil. Had one for 30 years, the other for 15 years.
You know, I wonder just how neglectful a lot of people REALLY are when it comes to diligent attention to vehicle maintenance. When I get new customers referred to my auto repair shop, part of my interview with them IS that very question.... "Have you done all the maintenance in a timely fashion pursuant to the manufacturer's recommendation?"
Invariably, they retort " Yeah, I've had my oil changes done and 'All that stuff'".
Invariably, these are the vehicles with cabin air filters growing 1/2 inch of mold, engine air filters of the 7 dollar ilk haphazardly installed and mangled and filthy. The coolant looks like my coffee, the brake fluid is the same color.... and the serpentine belt is typically original on a vehicle well north of 100 thousand miles, among other things.
Truth is, most of the diligent guys and gals who attend to regular things and are willing to spend what it takes to keep a vehicle up do not have these problems IF they employ someone who is conscientious in plying their trade professionally, or can and do perform these tasks themselves.
We can't force people to place their vehicles at a level higher than the water heater or dishwasher. I'm constantly surprised how different vehicles are turned into junk simply as a collective of broken items and neglected repairs/ maintenance. My wife's 2007 Kia Sorento was headed for the salvage pool when a friend of mine clued me into it, knowing I was looking for her a vehicle. It was severely neglected and FILTHY inside and out. She wanted 800 for it, and we settled for 300. That was August 7th, 2019. In the 3 years since, I've put about 2 grand into it's fix up, and it is now a dependable clean vehicle.
The engine was severely sludged, and with diligence and many BG flushes, it is finally not depositing large coffee ground chunks into the filter.
My current project is another SUV similar to my wife's Sorento. It's a 2002 S-Blazer LS that I bought for 300 dollars a couple of weeks ago. It's rear brakes were totally locked up, the fronts were barely better. The brake fluid? Black and gooey. Fuel filter was clogged, and the list just goes on and on. Today, I test drove it after 21 hours of time invested and over 2 grand total in parts were replaced. It drives, and stops like a dream, cold A/C, hot heater. The prior owner turned it into junk by neglecting it.
I've bought a handful of new cars/ trucks through the years. I began all of them on regular, consistent maintenance. Not one ever let me down in any major way. But then, I'm one of those nerds who actually, literally NEVER tows in overdrive! I've never experienced trans failure either.
