Dei review interrogation comes naturally somewhat early because oil purchases you to stock and not only when the oil lamp. Therefore, I can only take a position to supply. And that worked great. And the price is also hard to beat. Have ever looked - 1 liter 5W-30 brand cost around 17/18 Euro, 5 liters 55 to just under 70 euros. I believe the time is over for me. So I always have more driving pleasure - fuel LPG, oil on Amazon, let's see what I'm doing, then when I need new tires.
