I would like to know if any of you that are running an Evenrude E-tec had any powerhead problems. If so what was the damage,such as what did the pistons look like the piston walls and so forth. I'm conducting lubracation resurch and your inputs would be helpful. I have an 06 E-tec and have been using Amsoil HP Injector oil at a 50:1 mixture for the past 4 years instead of the Evenrude XP 100 100;1 oil without any problems at all. I have a strong feeling that XP 100 at 100:1 mixture isn't enough lubracation therefor causing the pistons to over heat causing major powerhead damage.
I did have the computer reset for 50:1 as recommended by the west coast factory rep to prevent overheating and damage.

I have used Amsoil HP Injector on the last three engines I've owned. including my 06 225 HO E-tec. I also have run it at the 50 to 1 setting and have absolutely 0 issues. When I pulled the plugs at 100 hrs and looked at the piston tops with a bore scope. they looked absolutely spotless. I did the same thing recently at 190 hours and the results were the same, spotless! I need to mention that the exhaust in the prop is extremely clean as well. I do put a can of SeaFoam in the fuel about every 3-4 fill-ups.
I also use the lower unit gear oil as well as a new product that Amsoil has to counter the effects of ethanol in the gas.
It is my understanding that all the newer E-tec HO engines can only be run at 50 to 1 vs. 100 to 1 like the older models.
Jim what is the new product for ethanol. I'm a dealer and I haven't been able to find anything about ethanol fuel treatment from Amsoil. I believe that the new E-tec's went to 50:1 is because the 100:1 is not enough lubracation and causing the older ones to burn up. I don't care what anyone says you just can't beat the protection that Amsoil give you. P.S. thanks for your input.

Here's another question.....
You have just spent in excess of $10,000.00 for a motor. Why wouldn't you use EXACTLY what the manufacturer has suggested (i.e. Evinrude or Merc or Yamaha brand oil), so as to alleviate ANY loophole for them to deny your warranty?
Wouldn't it be easier to ask if anyone that owns an e-tech hasn't had powerhead issues?

None here on my 2007 ETEC 225 H.O.
Marc, owe you a beer for recommending Tom's in Olympia, they are good.
I did the 300 hour service early at 180 hours.
I second Sessler, nothing against Amsoil, I would not give the outboard MFG anything to use in a warranty claim. XD-100 is all I run.
