Using the oil temp dipstick, I try to let her (01 - 650L) warm up to at least 40C, but she runs at around 100C. She'd never get to 100 idling. In additon, she cools off so quick the 20 minues after I shut her down, she's below 20C and needs to warm up again. Which is inconvenient as hell. What do yo guys do?
