Pop's '74 Chevy Cheyenne 350-4v long bed went 377,000 miles before engine replacement. He attributes this to the use of ARCOGRAPHITE 10-40 oil he used in the 70's and early '80s. Now '81 truck still running...

    I have a '83 K-5 Blazer that had a 305ci motor that went 306,000 before I put a brand new Goodwrench 350ci in it. I still have the truck. It now has 351,000 miles on it. In fact, I'm finally selling it. I really don't want to sell it but, I don't need two vehicles. That Blazer got me into some beutifull back country places in CO, NM ,WY and ( most importantly) got me back out. It never gave me any trouble and was always reliable. I have a 2001 Chevy HD Pick up on order. I only hope, my new pick up will be as reliable as my Blazer!

    Nothing like pencil shavings to make the motor run forever!!

    I was a dumass 14 year old when I bought a new '76 Kawasaki KZ 400(already had a Yamaha 90 dirt bike, parents said I had to get street bike to drive myself to work so they didn't have to!) Started running graphite crap in '77 and spun main bearings within 500 miles!!!Total of about 13000 miles on bike. ARCO actually paid for parts and recommended not using graphite in high revving engines. Lesson learned!! Fixed 400, sold it, bought 4 cylinder KZ650 at 15!

    '70s loose tolerance GM V8 engines with see thru oil filters. I remember very well reading an
    article in '77 - '78 in POPULAR SCIENCE titled "SLIPPERY OILS", they tested these two new
    Chevy Biscaynes with 350-2V low compression engines and used the ARCO GRAPHITE, they
    checked camshaft, cylinder walls, rings at 30K without engine oil change. The engine with the
    Graphite oil still had hone marks on the walls..

    I remember the stuff was a silvery black, hard as hell to clean off the garage floor, had to use Mom's shampoo for oily hair, cought hell for that one, friend tried it in his Volvo with dismal results, but th ole small blocks did ok. ARCO discontinued the product in early '80s. If you
    have to have the stuff, AMWAY sells an auto GRAPHITE additive for about $20.00 LONG LIVE MY POP'S '74 Chevy truck, I offered to buy it, he said NO!, he plans to drive it thru the pearly gates once they check his name off the invitation list book....

    My Father-in-Law's '90 Chevy has over 350,000 miles on it. Original motor! Original tranny! This truck is his work truck, & it still runs good! I just hope my '97 K1500 does HALF that good!
