Synthetic 2 cycle oils

[croixflats]

are all synthetic oils the same.Can all de used in boats. Is it true they get better performance and smoke less.I hear Amsoil is the best.

I rebuilt my Yahaha 150 paranoid about switching oils.

Be gratefull for some opinions

My merc all I run now amsoil in it. At first mine would smoke until I got all the old stuff out, Now it hardly does. Use it in the lower unit also.

I run both Amsoil HP-Injector and Amsoil lower unit lube in my outboard. I've got an early 80s vintage 60hp Johnson and I pre-mix the oil. I can't begin to explain the difference in starting, idling, throttle response, and smoke that Amsoil made to the motor. I'm running it at 50:1 premixed (maybe a bit richer) and my motor does seam to like it.

Need to put the Bat Signal out for the Oilman...he can answer that.

AMSOIL has 5 different 2-cycle oils - the need for so many caused by emissions requirements and the different types of motors.

For your 2-stroke outboards AMSOIL has 2:

Saber Outboard is for pre-mix only outboards - can be used as lean as 100-1 (now primarily the smaller engines).

HP Injector is for all oil injected included EFI, SDI, DFI and carbureted outboards: includes Mercury Optimax, Johnson & Evanrude FICHT and ETEC, Yamaha HPDI, Nissan & Tohatsu TLDI. It can be used as a pre-mix at 50-1.

Interceptor is designed for power-valve engines, such as most 2-stroke snowmobiles. some 2-stroke ATVs, most 2-stroke jet skis and jet boats. Interceptor is NOT Recommended for outboards.

Many are familar with Saber Professional in your augers, also for all your other air cooled 2-stroke utility engines - chain saws, string cutters, blowers, hedge trimmers, etc. Saber Professional is NOT Recommended for outboards.

The 5th one is Dominator which is AMSOIL High Performance 2-stoke. For high performance racing of all types of 2-stroke engines. When used in Outboards it is for short term use where motors are torn down and inspected frequently.

Oilman, I have a 87 Johnson, 70 HP, VRO. I'm bypassing the VRO pump and going to pre-mix my oil.

Saber outboard is the oil I want to use, correct???

[croixflats]

Thankyou so much oilman.I new my gut was telling me something and you put me at ease. Now to go out and get some hp injector.Be contacting you soon when finances straighten out

Reply to boilerguy:

use either the Saber Outboard - as lean as 100-1

or use HP Injector at 50-1

My choice would be the Saber Outboard, less oil so less octane dilution and therefore a little more power.

Oilman- I have a '95 75hp Merc that's oil injected. I should be using Amsoil HP injector. Correct?

[theoilman]

Yes, AMSOIL HP Injector is the right oil for yours, and all oil injected outboards: EFI, DFI, SDI, carbureted: includes Mercury Optimax, Johnson & Evenrude FICHT & E-TEC, Yamaha HPDI, Nissan & Tohatsu TLDI and more ...

Oilman,

I read this post too late and now have a full, unopened gallon of HP Interceptor. What can I do with that stuff since I threw away my receipt:(

Thanks,

BHS

Where did you buy it? If in a store you regularly do business with they should take back a sealed container (the gallons have a seal under the screw on lid). If you bought it on-line the dealer you bought it through should be able to get you a copy of the receipt (I just checked, no one has bought it in the last month through my referrals here on FM).

Or other uses: Interceptor is designed for power valve engines - most 2-cycle atvs, most 2-cycle snowmobiles, jet-skis and jet boats; but NOT outboards. (I know, wrong season now). It also will work in pre-mix air cooled 2-cycle engines (not the top choice, but will work).

This chart (bottom of page) gives all the which 2-cycle oil is best and which is OK to use for various applications.

NO, I didn't buy it from you.. Someplace in the lovely brainerd lakes area. I will take it back tomorrow and see what I can finesse.

Thanks,

BHS
