I have never seen a diesel Regal in person. The Cutlass was the most popular diesel G-body probably because Oldsmobile advertised diesels more than the other divisions.I've seen lots of diesel Cutlass'. I cant find any numbers on how many Regals got the oil burners.I have plenty of numbers so you should be able to guesstimate. The diesel was an option for three model years. 1982 to 1984. Two different diesel options. The 4.3 V-6 and 5.7(350) V-8. The 4.3 was rated at 85HP and 165 lb.ft torque. The 350 was 110HP and 200 lb.ft. In 1982, 223,397 Regals were made.134,237 were coupes.A total of 8,276 of all models received the gas V-8. In 1983, 224,507 Regals were made. 147,935 were coupes. Now I did find out they put 4,340 V-8 diesels in the Regal for that year since a gas V-8 wasn't on the option list. No breakdown on the number of 4.3 diesels. And for 1984, 219,343 Regals were made. No gas V-8 option. And the only diesel option was the 4.3 V-6. No breakdown on how many diesels for this year. BTW all of these models do not include the turbo V-6 cars in the totals. I'm thinking if you break out the calculator and put everything into percentages that should give you a rough guesstimate on how many oil burners were built. Here's some trivia since I have the facts book open. Cost of diesel option by year.
1982 4.3 V-6=$874 5.7 V-8=$924
1983 4.3 V-6=$599 5.7 V-8=$799
1984 4.3 V-6=$599
Compared to these gas engine options.
1982 4.1 V-6=$95
1983 4.1 V-6=$150
1984 4.1 V-6=$225
