Default Lifetime Revs Question

What does the Lifetime Revs mean? What does it tell me?

I believe it’s the Avg rpm the engine has been run.

I never really understood the significance of that myself. I have read and read about it. I guess I need a higher IQ to understand fully.

Nothing to do with RPM. It's a pretty useless statistic without additional info to go with it.

Here's an old discussion with lots of thoughts that might help (take some aspirin or advil first ):

This tells you that your engine made a revolution 2,587 times for every mile you've driven. This gives the savvy buyer information that you've spent far too much time in the lower gears hot-rodding your car! lol!

Just kidding, I think it's probably a useless piece of information telling you nothing usable from a practical perspective.

Only useful to the buyer of a used car. Easy to tell on a low mileage strip car.

….reminds me as I drove her one day with the G Meter displayed and the cautious way I drive, it states,
"really, that's your best shot?"

Maybe I'm a simpleton, but it tells me that so far in your car's lifetime you've averaged 27.7 miles per hour (15,778 divided by 570.1 hours) and your crankshaft has turned over almost 41 million times. (4080 x 10,000). That works out to an average of 1193 RPM. [(40.8M divided by 570.1) divided by 60)]

Short version - you treat her on average pretty gently. Maybe there's more magic to it than that, but call me crazy, I just go by what it says it is - Lifetime Revs divided by 10,000. 40,800,000 would look silly.

My average RPM works out to 1243 as of this moment.

OK. This is fun:

19921 / 390 = 49 mph
32,410,000 / 390 / 60 = 1385 RPM

In other words, lots of highway miles and also good MPG at 27.5

I just went over 100,000 miles today, so tomorrow I will have to look at that.

For an engine a better indicator than miles driven for whatever you used that to define! Engine starts would also be a very good indicator and the OLM keeps track of it as well, but info not displayed.

Lets see: Engine wear ~= # Starts x 1000 + lifetime revs!

Whats been said above plus it's a little "old school". Have you ever looked at the tach on a C1? Yep that number is there as well.

Exactly. I don't understand what's confusing about this. It's simple math.
