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.

Hi Arezfei,

Have you used Castrol Magnatec 10W40? which one is felt smoother on your CPS? I'm using Waja CPS.

hi, personally liqui moly mos2 would better than castrol. tested it on my old persona and indeed smoother and lighter pickup vs castrol.

Hi, many thanks for your review.. actually I've tried liqui moly 10W30 since it'recommended grade for CPS engine. It felt light and good trottling response but the engine sound was noisy and corse.

Any opinion if MoS2 additive would clog up the engine caused by sludge formation for a long usage (with normal range changing period at about 7000 km)? I know liqui moly is well known and established brand. Just curious..

I wonder if the 5w20 liqui moly is brought in to Malaysia..
