Pros
Cons
I fill it in domestic Zhiguli cars, and there are no complaints about the engine’s performance. I think that its body will rot before the engine asks for capital. With this oil, I understood what reasonable savings means; before that I had never been able to find a balance, good oils were very expensive, and cheap ones showed poor results, even at short replacement intervals. It practically does not burn out and does not leave shoe polish in the engine. In general, there are no disadvantages, I only periodically use engine flushes for preventive purposes, since the oil, although German, is in the entry-level price category, from which you should not expect miracles.  Aleksey: use Liqui Moly Optimal 10W-40 4L more than year |
I’ve been using my VAZ 2115 for 6 years, it doesn’t darken on propane - there’s no soot like gasoline, so I change it after 15 thousand km car mileage is 230 thousand km. I don’t add oil, enough for all 15 thousand no use Liqui Moly Optimal 10W-40 4L more than year |
I have an old 1995 car. Lately, it barely drove. I was using cheap Esso Ultra. Decided to try Liqui Moly. After 1000 km, the engine came to life!!! If before I tried to drive at low revs no more than 2500, now 4000 is no problem. The cleaning abilities are clearly showing. The engine used to overheat a lot, but now I've forgotten about this issue. Engine misfires decreased, and idle RPM stabilized. (It used to be 1500-1300, now it's 1000-800). The old engine got a new lease on life. Not found Vsevolod : |
