heheh barging in.
I suggest trying this new oil by Texas Oil that was called Titanium Revolution.I happened to be strolling by when i saw this uncle dude (boss) was doing the demo bout the viscosity of other synthetic oil compared to theirs.
Its actually quite expensive,cost around rm80 per litre!
and they make gearbox oil too.so i think its worthwhile for you guys to check it out. I was very convinced after seeing that little demo that he made about a machine that grinds bearing with a solid metal to see the wear.
All the other oils that was tried like Helix Ultra,Magnatec,Mobil 1 full syn was tried on a fresh bearing each then grinded to the machine.all develop alot of wear and sound of grinding metal. (especially helix ultra)
but after this titanium revolution oil was put into the test,it develop minimal wear and NO grinding noise what so ever.after the test was done,i saw the bearing became more shiny and polished..
heheh kudos man.i was really convinced on the product.guys go try it !
