Truck driven a million miles. After over two decades and 300 oil changes

Andy what the heck is a wire tbi plug?

My 90 Suburban has 390K on it and it still runs fine.  (It will probably break down on me now.. )

Don, it was one of the two plugs that connect the wires to the TBI....some people here may remember my posts of last Spring, it was driving me crazy to pinpoint the cause of the misfire in my engine.  I even changed the coil and distributor to no avail. I happened to be playing w/ the tbi while the engine was idling and pushed down on one of the two clips and the rpms purrred after that.  Went to the junkyard and cut off several from donor vehicles ( I have about 10 extras now).  I spliced it up and she runs so smoothly.

ifor a chevrolet truck to get past 300,000 some one isnt telling the truth someware...that enige had to be replaced right???

Could REALLY depend on how the guy drives it too.  If he is one of those guys that simply never gets over 2500rpm then the total number of revolutions the motor did in its life is going to be much differnt than someone that runs an engine up to 5,000rpm all the time.

So the miles driven is one thing, but the total time the motor was running vs. the miles driven vs. the rpm will make a big difference.

This is why an OTR truck can go 1,000,000 miles for the same work a city truck might need in 20,000 miles.



One other thing to consider is that this truck seems to be moving ALL the time. So the oil is staying up in the parts.  A truck that you rarely drive lets the oil settle in the pan and then the first minute of start up there is no oil on anything.   Heat cycling of parts.......Lots of reasons a truck being used will last longer than one that only makes short infrequent trips.

I am thinking a few years back there was a New york taxi driver that had a million miles on a Caprice.
