Would pouring them through a coffee filter tell how viscous the mix is? like say H1-R and Yamalube @ 32:1 and watch the rate it goes through the filter. Idk just thinkin'

I don't see why any builder should warranty a ported saw. If you don't have your Big Boy pants on don't come out to play.
Or you could look up the viscosity on the msds sheet..Would pouring them through a coffee filter tell how viscous the mix is? like say H1-R and Yamalube @ 32:1 and watch the rate it goes through the filter. Idk just thinkin'
They also tell u anything over 70cc has to be 33:1 also and for ethanol or poor quality fuel to use the hp oil not xp .I'm running K2 in VP gas for the 550xp. My dad keeps it and might use 1 gallon a year of mix in it besides when he goes cutting with me. It does seem to run better with less oil.
I've er placed several cranks in huskies run on 50:1 with oem oils including stihl ultra. I wouldn't trust it for a 372 or 390 at anything less than 40:1. Heck in Australia they specify 25:1 for the 3120.
Its great oil.Just out of curiousity does anyone use moterex oil at all ? Its pretty much the only oil In the mx scene hear , KTM make there dealers stock it and advertise it pretty hard
I know a Logger... His last saw, stock 461, lasted only 5 months on HP ultra at 50:1 before a low-end bearing failed.
First I'll disqualify my self in sayin' I don't have, and never have had, a ported saw.If someone runs a saw I ported on 50:1 and it fails...
The jug and piston will likely survive.......but the crankshaft will fail early.
The temp increases were very small and could be caused by many different things so let's not jump to conclusions.They also tell u anything over 70cc has to be 33:1 also and for ethanol or poor quality fuel to use the hp oil not xp .
Funny about more oil producing more heat with a temp gun all the karri fallers over hear swear that in summer if u dont run 3120's at 25:1 they get vapor lock and u have to refuel them while there still running cant turn them off ect..
Oil prices are the opposite hear also 1 litre of xp / ls+ costs me $13 and i actually bought some H1r a couple of weeks ago and it cost me $45 for a litre![]()
Gasoline is a pretty strong solvent too.. The issue with ethanol relates to the fact it attracts water,doesn't stay mixed very well and inhibits combustion in two cycles.First I'll disqualify my self in sayin' I don't have, and never have had, a ported saw.
But truthfully, the few crank failures I've seen in two-cycle engines were all running ethanol blend fuel.
I have my own (admittedly bias) opinion of why that is... but this ain't an ethanol thread, it's an oil thread. At the same time, oil is mixed with the fuel so I'll just say I find it difficult to expect optimal results after introducing a moisture drawing, powerful solvent into an engine that relies on residual oil for lubrication. In fact... I can see no reason not to expect the worst.
