Another angle I’d like to see is diesel regular/part/synthetic oil in a gasoline engine. I’m running a 1987 Toyota Supra Turbo with over 145,xxx miles but the head was rebuilt and the block was in great shape, oil is Rotella 15w-40 and the theory explained to me was these diesel oils have more wear and anti-shearing additives and it also cost less.
My question is – Is this the big secret Big Oil doesn’t want us to know?
from Shell –
The Energized Protection of Shell Rotella heavy duty diesel engine oils provides protection in three critical areas:
1. Acid Control – helps protect against corrosion from acids formed as fuel burns and as the oil ages
2. Deposit Control – helps keep engine clean for optimum performance and long life
3. Wear Control – helps keep moving metal engine surfaces apart for long life
