My '57 PV444 has been sitting dormant for about a year, so I'm going to get it out, go through it (check brakes, lube, tune, etc.) and plan to take it on about an 800 mile trip in June. I managed to get an original PV444 owner's manual on eBay, so I was looking at it to get familiar with all the specifications, etc. (Finally know how those goofy heater controls work.)
Anyway, the owner's manual says to use SAE 5 weight oil in the carb dampers. I have a PV544 owner's manual that was given to me years ago and it says to use SAE 10 weight oil in the dampers. I have a Chilton manual covering Volvos from '56-'69 and it says to use SAE 20 weight or automatic transmission fluid NOT 10W30 in the dampers! I've always just added some of whatever oil I was using in the engine when I changed oil and the car always ran just fine. Now with all this information at my disposal I'm really confused!
So, is there any opinions out there on what weight oil is best? Has anyone used ATF?
Thanks,
Bill
