Stood in the freezing cold and did an engine flush.
Ran the car for 15 mins.
Poured in Liqui Moly Pro-Line Engine Flush approx 750ml
Left it idling for 15 mins, then turned it off to let it cool down for 10 mins.
Popped out the old oil filter.
Sucked all the oil out through the dip stick.
Popped in a new oil filter.
Filled with cheap Petronas 0w30.
Ran for another 15 mins, then let it rest for 10 mins.
Popped out the 1st new oil filter. (which was already surprisingly dirty)
Sucked all the Petronas oil out through the dip stick.
Popped in a 2nd new oil filter.
Filled with Castrol Edge 0w30.
Jobs a gudden, apart from the frost bite in my nose and fingers.
BTW Castrol Edge 0w30 is only £36 per 4 litres on amazon, and free delivery if you have prime.
