nickg112 Posted December 17, 2019 Share Posted December 17, 2019 I have a 1941 Lincoln V12 and a 1948 Lincoln V12. Manual recommends straight weight oil SAE 10W, 20W or 30W depending upon temperature. I am assuming that non detergent because detergent oil wasn't available at that time. Since both cars have an oil filter, can 10W/30W multi grade detergent oil be used? Link to comment Share on other sites More sharing options...
JFranklin Posted December 17, 2019 Share Posted December 17, 2019 It is a good choice. If the car is new to you it might be a good time to drop the pan and have a good look at things before adding fresh oil. Link to comment Share on other sites More sharing options...
19tom40 Posted December 18, 2019 Share Posted December 18, 2019 Detergent oil was available in 1948, multi-viscosity oil didn't become popular until the late 1950s. A good quality multi-viscosity oil is a good choice. The viscosity improvers allow the oil to provide good lubrication at all temperatures.

Matt Harwood Posted December 18, 2019 Share Posted December 18, 2019 Use detergent oil, it will work just fine. Link to comment Share on other sites More sharing options...

crazycars Posted December 23, 2019 Share Posted December 23, 2019 Detergent. Non-detergent oil is garbage. Link to comment Share on other sites More sharing options...
pwlovely Posted July 21, 2020 Share Posted July 21, 2020 Would you not want an oil high in zinc? I use Rotella in my old cars. Link to comment Share on other sites More sharing options...
1941 Posted July 22, 2020 Share Posted July 22, 2020 I have used Shell Rotella 15W40 in my 1941 Lincoln for some 10 + years with no problems. I do change it once a year. Last year I had to drop the oil pan to correct another problem and found NO SLUDGE. Great Stuff and relatively cheap if you buy it by the case. (5qt bottles). I drive mine at least 3 days a week . SURE DO MISS THE MEETS Link to comment Share on other sites More sharing options...
larry butcher Posted July 23, 2020 Share Posted July 23, 2020 If you really don't know the history of these cars and how their V12 s were maintained; , JFranklin is correct . drop the pans and clean out the sludge , clean off the oil pump pick up screen and check the condition of the oil float. Good suggestion from "1941" good oil Link to comment Share on other sites More sharing options...
