Can't see if there's anywhere more sensible to put this ... We've just opened the bonnet of the car to find that the oil cap is missing and there is consequently no oil in the car but quite a lot all over the engine We suspect that the garage left it off last time it went for a service (er, quite a long time ago ), which is rather annoying.
Anyway, someone has just told us that we need to hose it off or our car is likely to burst into flames ... Is this true?
