Know is do.
I’ve been sending oil samples into a lab for an oil analysis (see reports below). We have found out issues with excessive wear.
I took my VCDS diagnostic tool and drove to my testing facility in mountains. The operating oil temp should be around 90 deg Celsius but it is a family car and manufacturers don’t expect constant heavy load around 80-100%.
RESULTS
oil temp 120 deg Celsius in oil sump (oil temp at crank shaft maybe 130 deg C)
SOLUTION
external oil cooling

[…] EGT aka Exhaust Gas Temperature – it is said that modern materials of turbochargers, head and exhaust are made from better materials. Garrett turbos are able to withstand temperatures of 1000 deg Celsius but who knows. My EGT was 750 deg Celsius when pushed hard – result is engine oil overheating as I’ve already written about in previous post. […]
