Correct. I live in the UK and most cars here are manual transmission 4 cylinder cars. 35 - 40 mpg from a 1.8 petrol sounds correct, I have had many cars like this and always calculate fuel consumption myself (never trust the trip computer) and get a steady 38 mpg average from 1.8 and even 2.0 petrol cars easily, even with mixed driving and conditions.

Dry the car with a cordless leaf blower, this should eliminate rust problems.
