I was pretty interested in Torco's MPZ additive so I thought I'd convince my mate to give it a shot in his 200SX (Same SR20DET as me). Hes been using Castrol GTX3 and I told him to dump the stuff for some real synthetic. Before he did that tho I suggested he try the MPZ additive to see if it really works. Added it in, and after a 50k drive we came across 3 things;
1) Idle vacuum gained 1 in/Hg. Before it was always pegged on 18in/Hg. Now its 19, and its NEVER been that high before. Friction reduction for sure.. Light cruising has gained slighly more vacuum aswell.
2) There was a slight tapping noise near the back of the head. Its completely gone now. Idle is alot quieter! Only the injectors make noise now..
3) No detectable change in power during WOT. Never expected a change either.
Seems all the FM/AW agents (probably just a bucket of moly!) they put in there sure works..
Just thought I'd share it with you. Now im pretty interested in their new Grp 4/5 oils, but I just put some 300V a month and that cost me a bucketload =(
