1 lawn mower, 1 pressure washer engine, 1 generator, 2 Audis, 1 Honda VTEC, 2 riding lawn mowers. They all seem happy. I have an Audi V6 12V (100,000 miles) and an I5 (80,000 miles). The Honda VTEC wants 5-30 to raise Honda fleet MPG averages...Honda can blow me.

The diesels (6.9liter V8, 230,000 miles and Yanmar 24HP I3) get Delo 400 15-40. The pressure washer pump gets CAT pump oil.

My neighbors bought one lawn mower from me that is 21 years old and still going. One riding lawn mower is 15 years old and going strong.

I'm not smart enough to own a turbo.

I'm a lot fussier about oil filters, antifreeze and ATF than I am about engine oil.
