Oil advice needed
Hi guys,
Just bought a 2002 ec 300 and i am wanting to know what type of oil to use as a premix with the petrol? also what ratio i need to use oil/petrol? Its the first time i have had a 2 stroke hence the silly questions. Cheers |

More oil = more power due to better sealing rings. It also means more smoke, more power valve cleanings, and more muffler repacking. On small 2 strokes it makes sense to go for more power but on a 300 I choose to go clean and have less maintenance so I run Amsoil Saber at 64/1 (it's designed for 100/1). Never run an oil at a ratio higher than recommended for that particular oil - lower ratios (more oil) are fine. The guide line I use is no ratio higher than 36/1 for non-synthetic oil, no ratio higher than 43/1 for synthetic blends, and no ratio higher than 50/1 for synthetics unless the maker of the oil recommends it for a higher ratio.

Here you go for the premix ratios:
http://www.gasgasrider.org/forum/showthread.php?t=182 I like to use 40:1 with a good quality 2T premix oil like Amsoil Dominator.

I run my 250 ec with 40/1 or 2,5% on Mobil 2t oil
We use the same mix on 125 Yz from year 1995 It's a bit too much oil but we ride on a soft sand mx track |

i run 50:1 super m, i've run 40:1 927 in the past. i like the smell of the 927 but it left more of a mess in my power valve. the super m burns cleaner but it's more difficult to get good plug readings, the color is a little off (kinda greyish).. i'm switching to 40:1 super m this spring..

50:1 is good enough if you use a quality oil.
Just in case you're not aware you need to use a synthetic oil designed for premix 2 strokes. You can use more oil e.g. 40:1 but I can't tell the difference and I prefer to have as little smoke as possible. I know others think differently because I often find myself sat on a start line choking & eyes streaming! |

I've used Putoline MX7 at 50:1 for over 5 years now without any problem that could be attributed to it. |
