Well my bulletproof SZR is coming up to 150k miles on it!!
Which oil should i be using when its this high, it uses a little, but this is to be expected with such a high mileage engine im sure! No mushroom clouds of blue smoke, and starts fine so im assuming its not too bad !
I've heard of people using a different viscoscity oil for high mileage, yet ive also heard people say dont do it because it blocks tappets??
What do you reccomend?
