48WingNut Posted January 21, 2007 Report Posted January 21, 2007 What's the right oil to use in these old flatheads anyways? 48WN Quote
norrism1 Posted January 21, 2007 Report Posted January 21, 2007 48wingnut, I used 10w30 in my 51 and had no problems. Quote
48WingNut Posted January 21, 2007 Author Report Posted January 21, 2007 Cool that is what I was thinking. How many quarts of oil is needed for a 28 230 engine? 48WN Quote
norrism1 Posted January 21, 2007 Report Posted January 21, 2007 My engine was the 218, but I'm pretty sure they all took 5 quarts and 1 for the filter. Quote
Reg Evans Posted January 21, 2007 Report Posted January 21, 2007 I don't want to stir up any trouble here but what about detergent vs. non-detergent oil in an old engine? Quote
oldmopar Posted January 21, 2007 Report Posted January 21, 2007 I don't want to stir up any trouble here but what about detergent vs. non-detergent oil in an old engine? That always was a discussion back when I owned a model T. Myself and most owners were using the detergent. One theory was do several short term oil changes with detergent to help clean the engine also read a theory that said the detergent would some how hold the solids and not cause a problem and then there are those that stay with the non-detergent. I liked the concept of a few short term changes then just stayed with the detergent. Ed Quote
Guest 51plymouthod Posted January 22, 2007 Report Posted January 22, 2007 ...and then there are those of us who use synthetic (in a total engine rebuild). I own 2 218's. Both are thankfully original to the vehicles. On the 51 Plymouth, it's rebuilt (0.030 pistons & -0.10 mains and inserts). I use Mobil 1 15W-50. This is a thin 50 when hot and, right or wrong, I feel it gives better lubrication to the crankshaft bearings at the relatively high RPM's these old cars generate at highway speeds. The '49 B-2-B has less than 45,000 miles and leaks some, but doesn't use any. On it I use a home- brew of 2 qts. 5W-40 synthetic and 4 qts. 10-30 regular detergent. Both vehicles maintain excellent oil pressure, hot or cold. Quote
Merle Coggins Posted January 22, 2007 Report Posted January 22, 2007 When I got my engine back together and ready for oil I had some Amsoil Series 2000 0w-30 handy and I didn't feel like running out to get dino oil for it. So it has the synthetic in it and runs fine, so far. No long term reports yet. Merle Quote
48WingNut Posted January 22, 2007 Author Report Posted January 22, 2007 Thanks guys! It sounds like everybody runs what they feel is the best. I was leaning towards the 10-30 but wasn't even thinking about detergent or non detergent. I'll figger something out. Thanx again! 48WN Quote
