My take

[Ausfahrt]

I consider myself as somewhat of a gearhead and I really like to take care of my vehicles. I currently have:
1997 Toyota 4runner 128000 miles
2002 Honda Civic 143000 miles
2004 Harley Heritage 23000 miles
2007 BMW R1200gs Adventure 13000 miles

I also own an outboard engine(4stroke), lawn tractor, as well as various mowers, chain saws, weed whackers, blowers, etc.

I have never done a UOA and I have never had an oil related engine failure in 30+ years of driving/riding which amounts to well over a million miles. I used to adhere to the 3000 mile mantra but now just do 5000 OCI's with dino. I do use Mobil 1 in the motorcycles because they are air cooled and I want the perceived added high temp protection in Florida summers.

Finally, I always thought that I had a severe anal obsession with engine lubrication until I found BITOG, now I realize that I only had a mild case.

Give it time, it will grow.

Ahh... to be such a young and fresh BITOGer. How I remember the days of not really giving a darn.

Oh, I forgot this part.

I contend that anyone with a newer car will be fine with 5000 mile dino OCI's and that in most cases the engine will outlive the body, transmission, and the owners desire to drive an out-of-date car well before the engine fails.

Unless you get lucky with some manufacturer's "sludge prone" masterpiece.

Good point. Too bad the dealers don't paste "sludge prone" across the windshields!

Give it a while, you'll soon be a lot worse
