I'm sure all these top of the line oils being suggested are great, but damn, I could buy an Earthquake shipped, for the price of what 2 liters of these oils cost !!
True you could always run the petroleum base at 4 oz gallon if you dont care about the smoke.I'm sure all these top of the line oils being suggested are great, but damn, I could buy an Earthquake shipped, for the price of what 2 liters of these oils cost !!
Good question. I suspect that the service life of stock or modded saws can be extended by providing more lubrication, though....Is the US market so large that they engineer everything to met regs here and just sell the same stuff the world over, or do they feel that 50:1 is the way to go with synthetic oil?...
For a saw with bumped compression I totally agree. I honestly don't know about stock. Not much harm in 40:1 anyway. I run the mastermind mix in all of mine just because my OCD won't tolerate different mixes laying aroundGood question.

Nah, mai putin ulei = mai multa uzura, rulmentilor nu le pasa ce licoare/brand special de ulei folosesti, ei vor volum de ulei, nu calitate. Stihl de ex recomanda in USA, Canada si EU 50:1 sa treaca testele de emisii pt ca asta le sufla in ceafa mai marii guvernanti. In Asia, Africa si America de Sud, pt aceleasi produse, recomanda amestecuri de 40:1 pana la 25:1. Dc? Pt ca acolo pot recomanda rapoate pt speranta maxima de viata a motorului. De ex in australia Stihl recomanda 25:1 daca nu folosesti ulei brand Stihl. Crezi ca zic asta ca sa le faca bani din vanzare ulei la alti producatori?Întrucât nu există o echipă vastă de cercetători în spatele meu și nu am 101 motoare de distrus pentru teste, trebuie să cred ce recomandă producătorul, adică un raport de 2% (de exemplu). Producătorul are tot interesul să vândă, așa că este interesat să recomande un procent cât mai mare, 3%, 4%...
Deposits only form when stale gas is used or a cheap oil, especially mineral oils. I ran a 461 for about 200 tanks of gas at 8:1 mix ratio on motul 800 off road just because its an old saw and it was a fun experiment. The exhaust was spitting out lots oil oil, but the sparkplug and piston/cylinder were spotless and perfectly clean. No deposits at the end of it all. Synthetic 2 stroke oils burn really cleanly and deposits forming if going too heavy on modern oils is an old days mythLegeaDejului - In the field of oils, Stihl is equivocal...
If there is too much oil in the mixture, deposits form. Those deposits come off in pieces and when a piece is between the cylinder and the piston ... another engine set?
When there is too little oil in the mixture, the piston is still scratched, but from overheating.
