Looks real good under the valve covers tho 
I planned on switching to Motorcraft with the next truck, but Idunno. This one is still running good the way I've been doing it. - Knock on wood.
Castrol isn't cheap tho, I just use the blend. |
Nope brew, I'm not opposed to Semi or full synth. but all I've ever used is Castrol dino. Good stuff, that Castrol, whatever type you use. I have never used it in anything that it didn't keep the inside absolutely like new. My motorhome is a P-30 chassis (454) w/54k mi. and it is like new inside and I never have had to add any in a 3k mi. change. Amazingly, it even stays real clean in the MH. I used Havoline for over 20 yrs. Used it exclusively in a Bonneville with a 403 (yep, Olds) that I bought new. At about 60k mi. I pulled the engine to replace freeze plugs ???, and the dadgummed thing had a lot of varnish inside (w/3k mi. oil changes), needless to say, I left Havoline behind and switched to Castrol and have never been happier. '04 is the only thing that hasn't had Castrol in that time.
