HD oil for first 20000 miles then Castro auto oil 5w30 from auto zone.Been using that for the last 30000 miles. No problems yet and much cheaper!
my mechanic used RevTech, has anyone ever heard of it, he used all the right weights, but I have never heard of this stuff, he also installed a RevTech oil filter. The guy owns his own shop, and is the President of the local Rolling Thunder, says he uses it and everyone else that he services. Just wondering about the stuff. Thanks
