Just wanted to know if I am making a mistake here. I got a 99 Beetle TDI cheap because it blew the turbo and the condition of the motor was unknown at that point. Sat for two years before I got it. Put a turbo on it as well as did the timing belt and all components to go with it. After all of that it started right up and runs like new so no damage to the engine from the turbo failure it seems. The mileage is 168,78x or so. I wanted to use a cheaper oil just to get any wear metals out since it had been sitting for so long and flush out any dirt that may have gotten in there from the work I had done. Absolutely spotless under the valve cover so it seems there is not much wear to the motor. I know it was very well taken care of all of its life. Figured I would run the Rotella T5 10W30 out till 170K and then start the usual VW spec oil changes. Just wanted to know if anyone thinks that this oil would be a bad idea to run for the 1,100 or so miles and then change out for a VW 505 oil? This car specs CF oil IIRC so from what I have read it should be fine on any diesel rated oil. I plan to use the correct oil for long runs but just making sure I am not going to hurt anything with the Rotella for such a short run. Probably will mostly be driven locally all highway just to make sure all is well with the rest of the car before taking it too far from home. Any comments appreciated.
