Hello everyone..I just picked up a 78 monte carlo with a 305 in it. No leaks or burning of oil that I can see. The car has 47k original miles on it and I was wondering which oil to use and if a synthetic or synthetic blend has enough additives in it to be sufficient in that engine. Or should I just stick with a regular dyno oil? Ive read on the forum of people using Mobil 1 with good success. Any help would be very greatly appreciated..Thanks again

A bone stock 305 does not have lofty oil requirements and anything on the shelf now is better than what was available back then. I'd probably run a cheap HDEO in 10w-30.

Agreed. Nice car. I sure wish I had my two-door '78 Malibu with the 305 again.

Synthetic would be a waste since a smog-era V8 would not be a good candidate for extended drains. I'd go with a decent high mileage dino, personally.

I appreciate the feedback..I was reading different posts of people saying you need an oil with a high zinc content ..Is that applicable for this engine too. I dont know much about the car since I got it last night but I wanted to change the oil and put the right one in

That's thing is well broken in so the need for lots of zinc shouldn't be an issue. That said, it couldn't hurt either.

If u recall correctly, those engines were known to wear the cam out because it wasn't flame hardened. It is a very cheap engine to rebuild and make faster.

If it was my car, I would use Pennzoil Yellow Bottle, 10W-30.

my 92 chevy 1500 with the flat tappet cam 305 got better fuel economy and the engine was much quieter when i started running royal purple hps 5w-30. i'd recommend that.

The 305s I had were hard on cams & valve seals-I would add a vote for Maxlife, in 10W30 or whatever weight gives you good oil pressure (at 47K it shouldn't matter). I miss my old '78 Monte, had T-tops & a 305, totalled in a snowstorm by an idiot with no insurance (not me).
