Engine oil Shell or PENNZOIL

Shell high mileage oil.

For the money, Pennzoil can't be beat, and I say that considering you can usually get it from Napa or Amazon around $7/qt. Idemitsu is also great, but hovers around $8 or $9/qt on Amazon or Napa.

Pennzoil Ultra Platinum 5W 30 gas to liquid base oil construct $26 for 5 quarts at Walmart or Amazon and is perfect for EJFA engines. People running 0w20 in these fbs and fas and ejs are just destroying their engine. I run the 5W30 pencil Ultra Platinum. I would get the mow tool but it's just really not worth it. I changed my oil every 2,000 mi and the gas to liquid technology. Making your base stock backwards from natural gas gives perfect polymeric structure and their additive package. It's just smoking!  I can get three 5 quart bottles for for $75 on subscribe and save from Amazon delivered plus tax. I think the 5W30s The Sweet spot. Unless you're tracking it then I'd go up to the 0w 40 in the Pennzoil Ultra Platinum. But you have to realize that the same company that makes the base stock oil out of natural gas also owns the additive package company and they run a a 48 Esther ad pack in this and it's just tremendous oil. If I had higher mileage I'd be running. Probably Valvoline 5W30 restore and protect it. Cleans the ringlands, wrist pins, valve train etc. But since I changed my oil so frequently, I always stay with the pennsville Ultra Platinum. I don't think you can be eat it at $0.16 per ounce it's just bulletproof to thermal oxidation.

Rotella T6 15W-40. I’ve used it in all my bikes, cars, lawnmower. It’s the best option if you own lots of motors. Just change it frequently.

I've been running Rotella t6 and a wix oil filter for years on my 04, 3k miles everytime, and it's currently still running with 245k miles.

First oil change after filling with T-6 on my 2002 Saab 9-3 (that didn't have a kit on it) I bought with 130k miles on it was really black, almost a bit sludgy. Next few oil changes quickly got better as the detergent broke down sludge in the top end and cleaned the motor up.

2013 Volvo XC 90. Owned since new, only used Penzoil Euro L formulation, all synthetic, 10W-30 and 143K miles later I had to get rid of her because I left the country. No engine issues at all.

I used Rotella T6 for the past few years and no issues

I think factory recommendation is Rotella but honestly you can go with any high quality oil. I have used Rotella, Castrol, and Valvoline synthetics in my 500 and I honestly don’t think it matters.

I used Valvoline synthetic in my first SHO, and I am using Mobile 1 in my latest SHO. I tried Pennzoil in my 5.0 (Windsor) and all the lifters started clattering.
