What weight is swepco 502?
I am currently running Castrol 20/50 GTX.
I see swepco 306 is 20/50, wouldn't that be better?

1 quart of Rislone in an oil change then a bottle of techron in a full tank of gas, Drive it hard for short rides after being fully warmed up, then in 1 or 2 months time roughly do an oil change again back to all oil.

the marvel myster oil seems like alot to put into the fuel.
Do people use the entire bottle?

NoVector

Per MMO: "Marvel recommends using 4oz of MMO for every 10 gallons of gasoline."

I do a full bottle in the tank every 3 months and a bottle in the oil right before oil change (add to hot oil let car idle for 5 minutes or so then drain it change filter..)

After an oil change with one quart of mystery oil, and half a bottle into the gas followed by a fill-up.
I ran the car pretty hard, and it ran well.
However after stopping and doing a hot start, it cranks slow and eventually started.
However I am getting the flashing gear indicators (automatic), the flashing hazard, and no power to the stereo, along with a continous door/key in ignition chime.
I think this is the loose timing belt warnings.
Any insight appreciated.

Cranks slow on a hot start, not news you want to hear with an AT.

Check the battery and related cables, hope its electrical.

Since adding the MMO oil I have been getting the warning that makes the gear indicator flash and kills power to the radio, and interior lights, plus door chime constantly rings.
I drained oil and added 8 quarts Castrol 20/50 high milage.
I believe the warning reset. Will test more in AM.
Owners guide does not speak about this warning.

Mrmerlin

what gear warning are you getting?
might it look like a timing belt tension warning?
look in the owners manual to decipher the light.

Has the flex plate ever been checked ?
was the rear pichbolt also checked /tightened

I had valve noise on start up and after idling for more than a few minutes once warm.

Swepco 502 was recommended by folks here and what a difference. No more valve noise on start up or after as long as 30 minutes at warm idle.
