1941Rick Posted May 5, 2011 Report Posted May 5, 2011 I brought my 41 P12 out of hibernation yesterday. Parked it in the garage at home. Now the better half is complaining about the smell coming from the car. As far as I can tell it is an odor from the engine. Could it be the non-detergent oil? ( freshly changed ). What are the feelings about running a detergent oil in a fresh flattie? Say a 10/ 30 or 15/40. Quote
Plymouthy Adams Posted May 5, 2011 Report Posted May 5, 2011 if it is a fresh rebuild you ought to go to detergent oil..I suspect you have break-in oil in there now? Quote
1941Rick Posted May 5, 2011 Author Report Posted May 5, 2011 I have just over a 1000 miles on the engine....Running 30 w non-det oil.....been reading up on it and opinion is detergent oil is ok for low milage engines..... Quote
Powerhouse Posted May 5, 2011 Report Posted May 5, 2011 (edited) from what I read...Detergent oil is better for fresh engines (after the break 500 mile in period-30W with break in lube to be used)...not for old ones. The detergent would loosen the crud in the old engines and track it through all the nooks and crannies. That could cause problems. I use 10/30 in my recent rebuild...under 1k miles on it so far.

1941Rick Posted May 5, 2011 Author Report Posted May 5, 2011 Just had a conversation with an Esso engineer and he recommends Mobile 1 15w 50.... Has the additives required for the flat heads...... also said to stay away from oils with a number on them of GF-3 and GF-4.... Quote

Powerhouse Posted May 5, 2011 Report Posted May 5, 2011 about $8.50 a quart...that's gotta be some gooood stuff. Quote
randroid Posted May 5, 2011 Report Posted May 5, 2011 Rick, When Pigiron ('48 P-15) is ready to go back on the road I'm going to run a synthetic oil because it has 10K miles on it and is thoroughly broken in. I haven't run it prior to this time because synthetic does such a good job the engine will never be entirely broken-in if run much earlier. Time for you to go to a quality detergent oil and enjoy it all summer. -Randy Quote
JIPJOBXX Posted May 6, 2011 Report Posted May 6, 2011 Might be cheaper if you give her a respirator? Just a question is this smoke from the vent pipe on the engine? If so no type of change in oil will take that smell away. Maybe a few green fragrance trees hanging from your mirror might help? Of better yet just buy a 42 Dodge convertible and keep the top down.
