code111japan 3 Assumed it has same effect as mori drive additives but that doesn't seem to be the case.I have valve tick on cold start that lasts for about 5-10 seconds (common on 1JZ-GTE). I tried Rewitec additive but it didn't help much.Once, I tried adding Mori Drive Engine Coat additive to HKS Super Oil and it completely cured the cold start valve tick! Engine was also running very smooth and silky. Of course, the effect disappears as soon as you change the oil. I assumed their oil will have same effect so I tried it but valve tick seems to be worse and engine seems to be running rougher right after the oil change.I will continue to use Mori drive additives instead of their oils.
