It is the heat cycling of start-stop, however, that does the real damage. Soot rapidly builds-up during cold operation, and moisture vapor turns soot into sludge, which in turn is the leading cause of seal breakdown, valve train wear, and stuck pinston rings. Moreover, water collects in the crankcase, causing rust, sulfuric acid formation, and thus greatly accelerated wear. | |

Some European small trucks now come with a manufacturer's recommendation of 25,000 miles not 3,000. And some trucks with onboard condition monitoring can recommend up to 50,000 miles between changes in good conditions (e.g. usage on long distance routes with little stop-start driving). | |
