Installation of a fully sequential Stargas Polaris system with 100l cylinder tank (approx. 80 l capacity) and Flashlube kit at 61,500 km. Preliminary considerations: Cost savings based on current prices. On 150,000 km, after deduction of the installation costs (2,700 EUR) about 5,000 EUR less should be smoked by the exhaust. I have been able to reduce the uncertainty of the gas newcomer here in the forum. Now I think I can use the engine less harmful and more durable than before. Let’s see. Selection of the workshop B.K. Autocenter in Dorsten about the reviews at www.gas-tankstellte.de. In the foreground were clearly proximity and quality, not the price. In my opinion, the price and cheap are just two different terms. Experiences with the engine were there, the work looks clean and the instruction was good. First impression after the test and home ride (approx. 80 km): runs as always. The luggage room has become smaller (for 2 people and for shopping there is ample space), but the range of 600 km and the reserve was more important.
