Hey hi there! Just took my brand new '10 Forester home tonight! Got a couple questions about what the dealer told me. I want to make sure I understood him correctly.
1. He said to not use the SportShift or cruise control for the first 1000 miles. Rather, to accelerate and decelerate "normally" for that break in period. Maintaining a constant speed (like with cruise control) didn't break the engine in correctly. I always thought the opposite was true; be gentle!
2. To *not* use fully synthetic oil in the car until it was 12,000 miles old. He said their chief mechanic told them that new engines don't "seat" correctly when brand new under synthetic oil. Reason is its so efficient, so slippery, that the engine rings etc. don't "seat" and break in right.
Is any of this really true or am I mishearing it?
