Dave: I've been running Detroits for 45 years in off road motorscrapers, mostly 8V-71s and a few 12V-71s. A friend of mine purchased a new Hancock 292 with a 4-71. He wanted to treat it well because it was the first new machine he had owned. At the first oil change, He used the highest detergent multigrade oil available. After a 1000 hours, his engine died. Tore it down to find that the ports were loaded with carbon and it had been flaking off and scoring the cylinders. Bottom line was that the good oil had a high fly ash content and it was burning and building up on the ports. He went to a oil that was low in ash in the new rebuild and it was still running well when he sold it 7500 hours later. I have always run staight 40W in my Detroits. It turns out that is the cheaper oil. I use 40W because in central Calif. cold is not an issue, 105' is! Detroit has a spec. on the limit of percentage of ash. I have forgotten it now, maybe has to do with that 45+ years running Iron. Good luck! Mel

Dad bought the 202 new in 1962, and I recall quite clearly going to the dealer with him to sign for it.
