The way you drive a car is more likely to cause sludge than the type of oil, an example being if you drove the car 2 miles to work in the morning and then in the evening you drove 2 miles back home.
When you drive your car always get it up too operating temperature before you shut it off.
If you have a thermostat stuck open and it is running too cool this can lead to sludge.
Many of the Syn fans here say that "cleanliness" is a true advantage. Even the Gp III is less likely to leave leave deposits, or break down, due to refinement. I would like to believe this, and use synthetic after some problems with dino and bad PCV valve making a mess in my Ford truck. However, I have not seen the theory proved. I am never sure what is marketing, I still think that shocking my stomach will give me 6 pack abs.
Remember the Mobil 1 oil in the frying pan....For now I believe....
Hethaerto's question is the one I would really like to see an answer to.
