What I wanna say is you can not believe it how much difference Motul 300V racing oil makes. Since I changed trans and lsd oil to Motul 300 gear three weeks ago, I have noticed that I get better fule economy and smooth and quicker shift,but I was absolutely suprised by Motul 300V engine oil. My car seems more sensitive and quieter than before. I used Castrol full synth before,not that good as Motul dose. Anyway, it is worth for your bucks if you choose Motul 300v.
