How about the lifespan of a 3100

[Dannymik]

I have the 3100 in my cutty...74,100 on it. Change my oil on the average every 2000 miles. I want to here what everyone with the 3.1 or 3100 has on there motors(mileage).

[phantomshado]

210,5xx on an 89 cutlass

284,913 in my 94 cutlass

[hoodilio]

84,000 on my 93 cutlass 3100v6.

[18incholdz]

148xxx on the 95 cutlass.....

[slick]

130,xxx on mine, with oil changed right around every 3000 miles. Still runs good damnit.

[Heza]

50,500k. the 3100 is a damn die hard motor. that's all you need to know.

[supreme_style21]

76,000 on the '94

180,000 on the '89

Wasn't on a 3.1L, but same engine design:

* 1988 Celebrity station-wagon

w/ 2.8L MPFI - 156K (currently)

* 1989 Beretta GT coupe

w/ 2.8L MPFI - 189K (body wrecked - motor strong)

The pushrod will last FOREVER if you take any care of it what so ever.

It's one of those engine that has to be abused to crap out on you.

99,4xx, still runs great. New Head gasket at 77,xxx. Doesn't use one drop of oil in 3,000 miles, that's when I change my oil.

[blugp96]

112,000 3100 No leaks at all, runs better than a new one. Oil changed every 3,000

[NOHC_WBody]

119K on the Gutlass

[Intlcutlass]

160K on my 89 with a 2.8

[92turboLE]

224,XXX on my 92 3.1 with no rebuilds - runs like a champ

74,300+ only problem with it were intake gaskets replace 2yrs ago and over do for an oil change

[runt]

94,447 on the 96 Cutlass with 3100...I'm bad tho, oil is usually changed about every 5k. I can't afford to do otherwise (I know it's not THAT much, but every penny counts) cuz of being a wonderful college student.

[PJB]

I saw one with 261k yesterday

[stu64]

36,000 on a '95 GP, the 3100 runs like new

[1990 Lumnia Euro Coupe]

153,000 On The Lumina. Runs Like a champ, uses no oil. I just bought it a couple of months ago, so only one oil change so far.

 

124,000 On the 1991 Grand Prix Same story, oil changed every 3,000 miles.

 

The 3.1 is a near indestructable engine. I've heard that if you take care of them, they will run forever. You can't beat 153,000 and not a drop of oil used.

 

I've seen them doing the same way 200,000 plus miles. I'll keep my two, thank you.

[vdaily89]

98,000 on a 94 3100V6. Wife's car and it is doing well even though it uses some oil and has a nice "ticking" where she drove it with the low oil light on for a few days before telling me....

[1990 Lumina Euro Coupe]

124,000 On my 1991 Grand Prix

152,000 On my 1990 Lumina Euro

 

Oil changed at 3,000 on Pontiac. I changed the oil when I first bought the Lumina and have not put 3,000 more on it.

 

Both never use a drop of oil. Both run like a top.

 

3.1's have cajones the size of the Liberty Bell when it comes to longevity. I've heard plenty of people say that you can't wear them out if they are maintained properly.

 

I'll sit on my two and see if I can milk 300 + out of them sometime in my lifetime.

[timbit_69]

i have 240 000 Kms on mine and its only a 95 (Police package) For some reasion they kept the 3100 in it. Its not an interceptor. i found out it was a daliy driver for one of the top detctives in Toronto.

 

i am getting my hands on the SC 3800 very very soon....

[airbe5car]

96k on the cutlass, runs beautifully so far....

[sl3196]

127k on my cutlass runs very good. Had to replace intake gasket, water pump, thermostat. (The dumbass who had it before me decided it was a good idea to mix Dexcool and the green shit.)
