I had of course bought on Amazon, for me the price.
My Toyota built in 2003 goes now much more pleasant in winter, no nag or nail more.The Mazda an acquaintance runs much more pleasant and smooth with the additive.
The biodiesel share of 7% in the diesel fuel is not really a pleasant fact and even not at all for the engine, many Japanese and even German engines older age.
After I poured the additive in a somewhat elevated concentration (of low temperatures due) before refueling the tank, you could see that the engine suddenly has more power and accelerates faster.
After the first 50 km with the additive showed me my board computer Mehrverbauch no, on the contrary, I've been saving fuel.
Approximately 0.3 liters per 100KM were average savings and that's noticeable at a tank charge and the high fuel prices at the time.
Positive:
- Engine runs more quietly
- No nag nail & more
- Noticeably more power when accelerating
- Fuel savings
- Improved cold start capability
- "Bad" improve fuel (if you have time fueled "low" and caught really bad Monday fuel)
