I just got a new toyota and I just simply want the most bang for my buck. I would like to have an extended drain interval but at the same time I don't want to accelerate the wear and tear on the engine.
Would M1 5W-40 provide better sludge protection in a Toyota 4runner engine than M1 10W-30 or 5W-30? I would like to keep the engine sludge free as much as possible so if anyone has any input, I'd love to hear it.
It never gets below zero degrees here. Would the M1 5W-30 and the M1 10W-30 keep my engine just as clean as the M1 5W-40? Someone told me the 5W-40 has more of a robust additive package. Does that not make much of a difference in the toyoya gas engine?
