One more question:when testdriving,i let them trash it after not more than 6 mins of normal street driving,but the car was driven to the local
shop and back one hour before the testdrive,so the engine wasn't ''winter morning'' cold.
I usually drive at least 10 mins before exceeding 2.5k,too bad there is no water and oil temp gauges and the only indicator is the fuel consumption.
In the mornings it starts at 10 MPG and i take it to 35 MPG,no trashing below 30 MPG.I know that the oil takes longer to warm-up than the water.
On the testdrive it started at 20 MPG,i am just careful with the engine and i don't want to take any chances,so was the testdrive too reckless in regards to engine stress?
