“The fill hole is the bit I'm stuck on. Does anyone know exactly where it is in an R60? Or can I just pump it back in through the same drain hole I took it out of? I only drained about 2L so I'd be putting the same amount back.”source ↗
“I got an oil change I checked when I got home like it is a good 20 minute drive should I drain some ?”source ↗
“I accidentally drained the transmission fluid instead of the engine oil. Then I added 5.1 quarts of engine oil to the already full oil pan.”source ↗
