My Posts This: Topic Forum | We use Amsoil Synthetic Saber PROFESSIONAL, mixed at @95:1 with standard unleaded. It can be purchased from:

A 1l bottle is about £13.00, cheap when you consider the ratios it should be used at.
I will leave it up to you as to whether you run it as intended, all I can say is we've never wrecked an engine and they run smoother and cooler than lesser oils at the 40:1 ratios.
No model shop or engine supplier is ever going to tell you to do this as they will invalidate your engine warranty, which may give rise to litigation.
We don't mess around with running in or different ratios for running in. Helicopter gasser engines aren't revving high enough to worry about it. We do run them on the richer side for about forty minutes and then just dial them in. Our engines take a good gallon of fuel before they come really good but that is normal. We change the piston rings after every 35-40 hours, we used to change them at 30 but it proved unnecessary.
One of our helicopters did 120 hours in Italy with a client without any maintenance. For various reasons that engine was knackered but it wasn't damaged by the oil.
95:1 was an arbitrary original mix that sort of stuck, it was me erring on the side of caution, at the time 100:1 seemed mad. |
Think most run in at this mix or thereabouts,up to you if you want to run in faster on a good quality mineral oil,then change to fully synthetic.Pays to stick with one good oil when you choose one as well.
It seems that this is an extremely good oil too. Anyone else using it got experience they could share?
