My last OCI I ran a Fram filter that I got as part of an Advance promotion with Valvoline Oil. There is definitely a difference in the color of that oil after 3K miles as compared to after using a NAPA Gold filter. It looks like there is tons more carbon or some other black particulate in the used oil. When I drain the oil after using a NAPA Gold filter, there is reddish/brown look to the oil. I have no idea if this actually translates into more engine protection. I run the NAPA filter for the better anti-drainback valve for just a little more money.

Nice sig BTW
The latest version of Delo 400 is what they call the "LE" version for low emission vehicles. Here is a spec sheet on it http://www.dooilco.com/pdf/Motor%20O...0%2015w-40.pdf Its Zinc and Phosphorous are 1300 and 1200 ppm respectively.

If it's SAE rated (SL and SM are the current ratings) it will be fine/great for 99% of people. Switching from one to the other will not produce positive effects. Don't add any mystery oils, oil stabilizers, or other wizardry, you don't really know what it will do to the engineered addative packages that are in the oil.

In the OP's case he is not 99% of the poulation. So far his Jeep has seen about 3500 miles per year. If he uses a quality synthetic oil and changes it once a year (12 months), he will likely save money over doing 4 conventional oil changes (every 900 miles and 3 months) per year. The combustion byproducts that get suspended in the oil cause it to oxidize and break down, so even with so few miles driven, dino oil would need to be changed too often to save him money.

Does anyone else here run Lucas? We run it in any of the vehicles we maintain ourselves. It's a good product that works.

I hope you're not talking about Lucas Oil Stabilizer, are you?

When you have a choice, buy American.

Very interesting. I ran lucas in my truck one oil change a while back and noticed quickly that the oil pressure went up about 10psi....not that I needed it to. Note, I don't run it anymore in any of my vehicles. I use castrol and castrol high mileage in my truck that has 120,000 miles on it. To be honest I have always used castrol mainly because I remember, as a kid, my dad always bought it. It has served me well over the years.

I am. My Dad has used it for years, and has had friends who worked at Lucas. He run Lucas in the trucks that he worked on for the over 30 years. He had engines on trucks go over 1,000,000 miles (yes, 1 million) before needing any major engine work. I believe the stuff in engines. I haven't seen a reason to not use it myself.

We've used it in old motors and it has helped improve cylinder shape and give a better compression. It has also stopped some of our older engines from burning oil as well.

please don't...

If you must: Go to your local mopar dealer and buy mopar combustion chamber cleaner. Follow the instructions on the can or the ones in the MCCC TSB.
