Is running in method a big factor on oil consumption for TSFI?
It has been for me and my previous VW TDIs. They've all been run in nicely with lots of variety in engine speed, with the occasional incursion to 2/3 throttle, for the first 1000 miles, and none of them have used a drop of oil between services, given good economy and a decent power output. There is one exception. A 140TDI Golf MK5 GT I had was bought from VW Lookers in Burnley via UKNEWCARS and driven directly from the dealership down to relatives in Southampton. That car pretty much sat at 75mph in 6th for the first 300 miles (did the same going back to Newcastle a few days later), and I think it must have glazed the bores. That car was sluggish, thirsty and used a litre of oil every 1000 miles.
