It doesn't have a cat either. Truck sat for 3 years I revived it runs great changed the plugs 7 of the 8 were good and clean white in fact the number 8 plug was badly fouled from a non functioning plug wire it was missing badly when this was happening and is not now. I am stumped. truck shows 67k miles which seems very much to be original based on the condition of the truck.
it needs a period of cleaning, if it was mine? I would buy a better quality filter that cleans the oil of smaller contaminate for a longer time and purchase some high quality oil that is synthetic in design. They all claim the best right? Well I have used many brands at one point in my experience and I'm still operating fairly well for a good amount of time now.

I do long drains and use Oil Samples to determine condition instead of changes, I am glad I have taken this route.

I started off in 1997 using Royal Purple in a 428 CJ Mustang GT the instant I started the engine I was floored I had to retune a tuned carb down 300 rpm just by changing the oil in a hot engine, Right there I was convinced that for years I was getting boned real good by ASE store shelf oil.

I settled with a company that pays me back something when I buy the amount that I buy every year, So I'm good. g
