Hey guys, i have a 1976 eldorado and ive been losing oil like crazy since i got the car, the strange thing is that the block is dry, i
have no leaks from the oil pan, and Im not getting any blue smoke, only bad smoke is the white smoke in startup. Ive been using
valvoline 10w 40 which was recommended to me, and i dont know if the engine is just eating the oil up, any suggestions?

Re: Losing Oil in 1976 eldorado
Are the valve covers stock? I would double check the PCV and breather to make sure it isn't sucking oil form there. The Valvoline 10-40 is good oil for today's cars but probably doesn't have enough zinc for your engine. I wouldn't drain it right away but next oil change you should try a 15-40 truck oil.
