I know that I am probably going to open a can of worms here. But, I would like to know what other PM drivers are using for motor oil.
I'm of the "old school", and I'm having a real hard time accepting what Ram says I should use for motor oil. The thought of using 5-20 conventional oil in anything gives me the creeps, let alone leaving it in the motor for 10,000 miles. I'm a synthetic oil fan and used it in my old Sprinter as well as everything else I own. The Sprinter also had a 10K oil drain, but I never let it go that far. I would usually change it somewhere between 7 to 8K miles. I realize that I can get the 5-20 in synthetic, but again, I'm having a tough time with the 5-20 thing. To me 5-20 may work in a car, but a truck, carrying a load and or pulling a trailer should have something else for oil, like at least 10-30.
Depending who and what you believe and or read, the reason for 5-20 is so the auto builder can improve their CAFE standard. The 5-20 will work for the duration of the factory warranty. After that your own it, along with any premature engine wear (if any) caused by using such a light oil.
I know oils have come a long way, I'm just wondering what every else thinks.
