I would take a good look at the brake fluid and stale gasoline but the rest should be fine.

The interesting part is that the T6 was used to tow a camper from Indiana to the Oregon coast where we are now. It’s interesting to see the viscosity, flashpoint and Moly are higher in the T6 even after towing through the mountains and more miles on the change.

Pros: higher viscosity

Mileage: 7886 km

I had been using LM in our Euro vehicles for years until prices started to climb. I switched to the appropriate Mobil 1 oil earlier this year. There is not enough difference in test results to make me stay with LM once the price difference became as big as it was during my last TDI oil change.

Pros: appropriate oil, years of use

Cons: price started to climb

Vehicle: Volkswagen Beetle
