Well, I have had the car less than 2 years and have only driven it for about 14 of those months (winter storage). But, I've done over 17,000 miles, that's over 1,200 per month...one day here one day there...when it's nice out. So, I drive, and clean it. I don't have time to search & see the engine!
I've seen the underside of the engine, does that count for anything?
