I am contemplating changing my outboard motor oil. I have a 90 hp Johnson 2 stroke. It is a 2001 and has only had Johnson/Evinrude oil in it. I am considering changing to a different brand of oil for two reasons.

1. Hassle to get Johnson, have to drive to the west side of Pensacola.

2. Expense. It is now costing $30 a gallon.

Do you use OEM oikl? Those of you with Johnson/Evinrude, do you use their oil?

What are the mechanics thoughts on this subject?

I have had 4 new 2 cycle outboards on my present boat and have NEVER used Oem oil I use the cheapest TCW3 oil I can find and have never had a problem. The mechanics that work for dealers will tell you to use oem oil and of course the dealers will tell you the same thing. I even had one tell me that if I changed brands it would cause problems with the way the oils wouldn't mix correctly. Well I'll be damed they do mix correctly. In case anyone is wondering why I have had four engines on my boat, It's a 1989 boat...

I have done some searching for an oil I trust that was not OEM. I found one made by Warren Oil Co. I have used it for 12 years on engine rebuilds, breaking them in, and on personal boats. I have never had an issue with this oil on regular carb and fuel injected engines. I have not used it on two brands of direct injected engines yet. ( optimax, and e-tec) It does work good on the HPDI Yamaha brand. I will be using it with optimax also. I will not use it on E-Tec because I will not work on those engines and do not know enough about them to be able to safely say. The oil is the walmart brand supertech oil in the <U>blue</U> container. I have seen the white containers, but they have a different manufacturing code and I have checked who makes it yet. But, the blue container walmart brand is a very good oil and is under $9.

I am realy surprised. I thought a lot more boaters/mechanics would have had an opinion about this.

I was wondering the same thing. MyOptimax is out of warranty. I've alwaysused Opimax synthetic oil. When I got the boat in 04 it was $25 a gallon at Marine Max, now it'saround $36, about $25 at Docs if you have your own container. Now that thewarranty is outI was thinkingof switching up. Academy has Penzoil synthetic for $17.99 and just ran it on sale for $11.99. Thats a pretty significant savings. Another question I have is do I need to drain what's left of the Optimax oil before putting Penzoil in the tank or can I mix the two?

west marine TCW3 or quicksilver TCW3 - never used Yamalube in my 2stroke 90hp Yamaha and I've had 0 problems.

In all my years of running outboards (all 65hp or less) I have never used OEM oil, and never had to rebuild them due to a oil problem. Only had to rebuild a Merc 3 cyl 65hp due to overheating top cylinder...took care of that problem by adding more water to top cylinder.

I have a 2005 60hp merc and i use the merc oil from Docs marine for about $25 a gallon (first gallon i bought in a container for about $2 more and have used the same container). if i had a larger outboard and used more oil i would probably be thinking about switching to something cheeper but for now atleast im going to stay with what im using.

Royal purple gave me no economic benfit that I could see. TMS highly recommenedd it, but my boat runs great since ignoring them. I ran Yamhaha on West marine TCW3 for 600 hour, no problems at all.
