Go to your local Chevron oil distributor, and buy their 2 stroke, is is just as good if not better than Quicksilver or Yamalube. And no they will not void a warranty if you do not use their non branded oil. Just make sure it has TCW3 rating. Makes no difference if mineral or synthetic.Yes. Seriously.
Right. It is "special" marketing to suck more $$$ out of the buyer. We have been running direct injection since the early 2000's with the first Yamaha OX66's came out. Still run a few of the OX66's and HPDI's but have largely moved to OptiMax over the last 5 years on the 2-stoke side.It is NOT normal TW3 stuff. Its special for direct injection.
