That's what Shell says but has there been any independent testing with other brands of oils that show this piston cleanliness?
All the brands tout their products. That's expected.
True I feel these companies have become loose with the comparison figures. However, you can't make stuff up either. Mobil remains the best in this area.
Mobil's marketing and advertising imo is the best in the business. Pennzoil is beginning to slip a bit it seems.
