I worked at a Moble station for years doing automotive inspection, I've seen the 3800 V6 powered vehicles come in with 300, 000 miles and still pass the emissions test with flying colors! Same emissions as a new vehicle after 300, 000 miles and if I'm not mistaken the only engines to do it time and time again, that is to say there where others that would pass that had high mileage but none as consistently as the 3800!🙋‍♂️

I loved that 3.8 Buick. I had one in a Buick Skyhawk and that thing was fast, it had great acceleration.

Pffft.... let me tell you qbout a slant 6 my mom had in a Volare.... she bought it with 259k on it for $600, daily drove it for 12 years. She never changed the oil, checked the coolant or even did tires or breaks. It completed 2 trips annually from Rockland Maine to Albany Kentucky. In the end she sold it to a guy we knew named Ed in 1995 for $600. He is still driving it today in florida...Florida.... no rebuild.... ever. I'll ask for a odometer reading and a pic.

Had over 300.000 on a 67 slant six, have 245, 000 on my 07 5.7 hemi, my son has 365, 000 on his 07 5.7 hemi and I know of more than just a few 318's that ran over 300, 000 miles.

I have a 1978 Benz 300SD ( early car ). It motor has 733, 000 miles on it great motor. Also have a 1983 Benz 300D that has 677, 000 miles. Just keep valves adjusted and change oil every 2500 to 3000 miles. They can go for ever.

[erichouck]

my 1994 Ford Ranger with a 4.0L OHV had 385, 000 when I sold it and it was still going strong

[Pococnosurvival]

Silverado with a 305, had over 600k when I sold it and still ran great.

[RichardWilson-shkr]

You missed the Honda V6 J, just went past 320K miles. Still gets 30 mpg and beats most to the next redlight.

[sethstanleystowellviii]

I just sold my 97 Toyota 4 Runner with a 3.4 V6 that had over 425000 miles and still running today.

[jamesburian]

I would make at least one exception to the buick engine. Series 1 3.8 was great. So was the supercharged 3800 series II. But the normally aspirated 3800 series II had one major problem. The plastic intake manifold would crack and cause hydrolocking when coolent leaked into the cylinders. These could leak as low as 50k-70k miles. Other than that and the plastic coolant elbows used into the water pump they were reliable. Replace the elbows with metal and the manifold and you are good to go.

Forgot the almighty Barra I6 from Australia 💪 and its father the SOHC/intech I6 4.0, indestructible.

[mikewilliams]

My 99 accord 2.3 has 430k and still kickin.

[Greg-lyrz]

I don’t believe the Buick 3800 ever powered a ‘65 Impala or any ‘70 Oldsmobiles.

Back in the 80’s, I use to drive company service trucks. Most of the trucks were newer Ford trucks with the 4.9 liter engine and automatic transmission. One day, the owner gave me an older Chevy truck with a V-6 engine and manual transmission. Not only was the Chevy faster than the Ford trucks, it got impressive gas mileage too. I drove the truck to San Antonio and back and was shocked that it used little fuel compared to the Ford trucks. I’m not sure what happened to that Chevy truck but the owner must have sold it because it was a great truck.

[garyk]

I had the Toyota 22RE motor in my 4x4 pickup 230, 000 miles on i sold it to a friend of mine he used it for dragging fire wood its still running with 300, 000 miles on it

Look, I love great motors, I have a 5 liter V8 Mercedes cabriolet in the garage. However, what do I drive every day? An E class Mercedes 270. Now this was part of a three motor range Turbocharged Diesel. Straight motor. You had 3 choises. The 2.2 litre four cylinder which taxi drivers loved, then you add a cylinder, you get a 5 cylinder 2.7 litre. 170bhp will do 140Mph. That is what I drive to the shops and is unbreakable they will do 500km+ Then you get to the 320, they have added an extra cylinder, straight six. The motor is brilliant. I love straight six, owned and crashed a Triumph. The 320 engine was brilliant but too heavy it squashed the front suspension.

[sgtcrab]

The Mercedes 5 cly diesel was great! The 4 cyl NA Mercedes diesel was the Taxi cab engine of choice in Germany when I was in the Army. (65) Absolutely bullet proof. Weak and slow...but as a taxi in a city it was GREAT! 190 D generally.

They forgot to mention the Daimler Chrysler 3.5 Magnum V6.
Guaranteed to go 300, 000 miles.
