I started a new thread since my last one got split up till I couldn't follow it. Since I'm concerned about a noisy lifter I was wondering what oil should I use? I live in the desert in AZ. I've heard the lifter problem for awhile but it seemed to start to correct itself.
However after the last oil change I think its gotten louder. So what oil does everyone recommend. Maybe I'll change it and see if it helps the problem.

Sir: If it is a sticking lifter you can hold the engine at a fast idle and slowly pore about a pint of automatic transmission fluid or marvel mystery oil into the top of the carb. It will smoke like heck but usually will clean a sticking lifter. This is the only thing I know to do externally.
As for oil?? I use 15/40 Rotella dino.

Shell Rotella 15W40 Dino oil (white bottle). It is available at AutoZone or Walmart.
You can go with one of the synthetics but they will not have as much detergents as the Rotella.
If you can find one of the other brands of CI-4+ rated oils like Deluo they are fine also.
What you want is something that has CI-4+ and NOT CJ-4 on the label. I'm hoping that the heavier detergent oil might loosen up a piece of dirt or sludge and free up that lifter.
If it is indeed a mechanical problem rather than a contamination problem, then nothing you do with oil will make it better.

Chuck,
I do not think that will help if it is indeed a sticking lifter. Pouring it down the carb will never make it to the actual lifter. If it is a sticking valve or ring that will work fine. I have done this to several engines. I usually add about 1/2 quart slowly and then increase the rate until the engine dies. Then I let it sit overnight and soak. I start it again the next day. It will smoke until the exhaust system gets hot enough to boil / vaporize all of the oil coating the insides of the pipes and muffler.

Please excuse my skepticism, but I fail
to understand how ANYTHING put in through
the carburetor can reach the hydraulic

lubrication system.

So, where are you putting the supositories? In the carb or in the oil fill?

I had always heard that you put the transmission fluid in the oil fill, drive it for a short distance, then change the oil. The extra detergents in the ATF were supposed to free the sticky lifter.

I always liked Mobil synthetic 15-50. I am currently using Rotella 5-40 Synthetic CI4 + . The only reason I switched to Rotella was it had more zink but now Mobil and Rotella are the later formulas so the are probably similar in zink content.

Since I have a little oil leak I'll prob not do the synthetic. So is 15/40 the correct weight for non-synthetic?

If I wasn't going to use a Synthetic oil one of my first choices would be Rotella 15/40 and a zinc additive if you have to use an SJ type. The reason I liked the Mobil 1 15/50 was at 40,000 + miles the crankcase was very clean and the cylinder walls had only 8 ten thousands of wear. I tow a small pick up or an inboard boat most of the time across a hot desert so I like the higher temperature rating of Synthetic oil.
