I had an 1981 Deville with the V6, when you ordered that engine they gave you a $150 credit off the price of the car. This engine was offered from 80-82 in the Deville and FB and from 81-82 in the Seville and Eldo. But almost all V6 Caddy's on the road back then were 1981's. Even a neighbor up the street had a V6 DeVille and his was a 1981 also.
I have an '82 Fleetwood Brougham with 85K with the 252 V6. Very reliable and moves quite well. I average 28 mpg on the highway which is pretty darn good for a land yacht. I'll never give it up for one of the new plastic cars being produced today.
+Gregory Maus That's unbelievable that an '82 Caddy can get that mileage. Would be great if you drove it daily. My '78 Eldorado is rated at 10/15mpg. Doesn't seem like it uses that much judging by the gas gauge cause it has a 27 gal tank, but when you fill it up you realize all the gas you've used lol. I was reading that the 4.1 V6 actually makes the same HP as the 4100HT but more torque. I bet so many Cadillac buyers back then insisted on having the V8 just because they thought it was more powerful.
I had this car the day I got my DL back in 96’ . My first set of wheels. $800 . I was 16 yrs old . I pretty much destroyed the engine driving up to the mountains to snowboard one day. I’ll never forget how uncomfortable it was having my dad drive me back up there to get the car later that night. I don’t believe he spoke a word to me for the entire hour plus drive.. I was supposed to know that it wasn’t strong enough to go 80 up the grade, loaded down with me, 3 friends and all our gear! Lol. Looking back I shoulda been creeping at 30mph up the Lee Canyon road. Live and Learn . My next car was a 76’ Monte Carlo. The 350 had a lot more power . Not close to the power of my dads 71 SS454 Chevelle (that I borrowed a time or two) but it had a lot more than the V6 Caddy.
Though a bit undersized for this car, the V6 was the best engine choice in 81 and 82. 1981 was the V-8-6-4, then 82 and beyond was the V8 4.1 POS, Ooops I mean HT
The HT4100 The 6.0 8-6-4 and the HT4100 are nothing alike in any manner, nor is the drive train behind the motors. One is great, the other is really not good at all. The 8-6-4 is a big block Cadillac motor with 6.0 liters based on a proven platform that has set high mileage and reliability records. The 8-6-4 has been known to turn odometers well past 500K miles with no major failures. The HT4100 is a tiny aluminum block 4.1 liter motor with cast iron heads It had very little power
It had very little power, even less torque, with a small transmission (that failed too) and tiny differential behind it. In other words, if you wanted to change an HT4100 to a better motor, it goes much deeper than just the motor
This car can achieve 18 to 29 mpg which is so odd for a car this size, and the 4.1L V6 was the most reliable (with overdrive although slow) along with the carburated 368 V8. Most of the HT4100, V864, Diesel 5.7L and 4.1L V8 are long gone.
V-6, couldn't get out of its own way, forget climbing hills or trying to pass w/full load. No gas improvement because of constantly flooring it just to keep up.

My neighbors had an 81 the same color combo, but it was a diesel. They bought it brand new.
I have a yellow 80 Coupe Deville, and my name is also Miles!
I hear that's the engine they gave the old guys who needed something to complain about
