Hello, at my Golf 2 (see Sig) I noticed recently that it takes a long time (18-22km) until it is at operating temperature (80°C oil temp).Now my questions are: 1. Does this come from the lower combustion temperature of e85 gü. Superbenzene? 2. Due to longer warm-up the engine is subject to higher wear, but what for the reason that the engine is damaged by e85, right? 3. Is it vllt. on my thermostat, which is 4 years old? I observe this problem. since I completely switched to alcohol (mid-September, 6000km, continuous filling with ca: e67) but I didn’t think about anything. Vllt. can you help me or confirm one of my conjectures.
