i researched online and got interested in liqui moly products. Too bad nobody did any thorough review on it yet, so i took my chances with one. I was thinking of getting the toptec fully syn, but decided against it as i am interested in the mos2 additive. Thus, i found the mos2 leichtlauf 10w40 oil with the mos2 pre-added.
I've been using fully-syns before, and i must admit - i got used to the appearance of such motor oil. What i'm talking about is the 'clear' looking new motor oils, be it mineral, semi-, or fully-syn.
Mos2 leichtlauf 10w40 however, caught me by surprise - it is dark gray in color, and it's not clear. It's slightly 'cloudy' due to the added mos2 additive. The service centre peeps were surprised too.
After pouring it in, i noticed the immediate effect on the first start - upon ignition, the engine cranks to start smoother, and somehow a hair quieter. Subsequent test drives proved that the engine felt 'silky', and not so harsh even when i revved hard. Overall, i love the feeling. The car felt lighter to accelerate, and smoother when cruising. Since i travel the highway daily, i can consistently gauge any improvements on fuel economy. Overall, i get slightly better fuel economy.
To deal with any possible placebo effect, i handed the car to my friend, who drove a similar car. We're always benchmarking each other's car, and he knew my car pretty well too. After a quick spin, he informed that the engine runs smoother throughout the range of the revs. The effect was almost like running a higher compression than before. After googling around, i found out that mos2 was designed to as micro-sealants, to effectively 'seal' microscopic gaps between the cylinder wall and the piston ring, thus eliminating friction and preserving compression as a bonus.
I'm also eager to test liqui moly's ceratec additive, but when my friend poured a can into his caldina, i was surprised yet again. It looked exactly like teh tarik. I can't comment much other than appearance, since i haven't used it before.
P/s: My engine is the notoriously noisy, thirsty sp4h cps.
