Thanks Fellas for your replies. And GTX1a1, you're not a wise *** I know, but yea that was a kinda wise *** question. I grew up in a CPDJ dealership, small town, family owned. Dad was old school of course and our market catered to the four door, stationwagon, truck customers. And dad would occasionally order some muscle cars over the years. But not much up until about '67-'68 when Mopar muscle cars were selling like hot cakes. So even though I lived and worked there I seldom ever had the opportunity to do an oil change on or much less drive a Hemi car. There just weren't any around. And yes I know that the owner's manual listed several viscosity grades per expected driving temp range, etc., etc. But the motor oils we have these days are a lot different from those back then and so is ATF, etc., etc. And especially the fuels available now. So for all you guys who are in the Hemi know, you let me know. I'm here for two reasons; to learn and to read all about the cars I grew up with that so many folks still love, fix, rebuild, drive or race. I would like to add one more thing as well, I'll probably have a lot more dumb *** questions to ask in the future. But isn't that how we all learn? Thanks again fellas. And Meep-Meep she is a really nice car. 68-383GTS, that's exactly what flashes through my mind every time I pull the cover off of her in the garage, WOW! I can't believe your mine!
