Me again with a silly question, please bear with the grease monkey.
What is the liter capacity of a 31 cehvy fuel tank?
Reason I asked, I haven't had a chance (yet) to go to a filling station to fill her up as she is still in restoration.
I wondered because I need to know how much MMO to put in with each fill up.
Thanks

My 31 coupe has a ten gallon gas tank on it. You can figure out the litres from that.Why are you putting MMO in the tank? I do not use any additives in mine. So far I have put almost 4500 miles since it was restored and have not had any problems with it.

Now I'm confused ! I might have a sticky valve myself. What should I do ? Sounds like Cyl. # 5 .

MMO. i understand why it would help prevent a sticking intake valve, i have only had sticking exhaust valves. is it not burned in the explosion and so can lube the exhaust or what???

I have used MMO top side and soaked the valve stem and valve guide and then tapped on the valve stem (rocker arm & shaft removed) to loosen carbon around the valve stem inside the valve guide until the valve spring pulls the valve up when it is tapped down with a hammer. Sometimes an aftermarket umbrella valve stem seal will work to well keeping the overhead oiling from lubeing the stem inside the guide. I have had this happen on a 235 head a modern machinest reworked and set the valve stem/guide clearances to values for a modern Small Block V/8. After 450 miles the exhaust valve stuck and bent the pushrod.

Just curious,is there a downside to using MMO mixed in the fuel? I have been using it since being advised to do so by a VCCA member on the chat some time ago---probably gone through 10 full tanks of fuel so far----should I not use MMO or is it strictly a personal preferance,or a waste of money,or detremental to the engne??? I put huge amounts of faith in the info I get from all the members here----I am certain they ALL know more than this rookie!!! Thanks,Jay

The only down side effect I can think of may be higher operating cost if you add a lot to each tank. Of course if you use too much MMO/gallon of gas it may foul a plug before the engine gets warmed up. I use about a cup to 10 gallons, about every third tank in everything from weedeaters riding mowers walkbehind mowers, trimmers, roto-tillers, old Chevrolets to the 2005 Tahoe. I also MMO to fogg the engine of anything that sits in the shed over the winter, and it doesn't seem to affect the starting next spring.
I also use some Seafoam to stabilize the gas for a couple of months, to a year.
