Engine Runnability relating to oil quality

Does quality of oil affect runnability on engines ? I have a 1993 Johnson Faststrike 175. On an older engine would it matter ?

I would spend the little extra money and get the Johnson/Evenirude oil. I think in the long run it will help out your motor for length of life and smoothness of it running.

Just my .02

I most certainly agree with that. Run the motor oil that is made for your outboard by the manufacture of your outboard. The motors are way to expensive to run anything else in my mind.
Thanks, Bill

Me personally I will run nothing but 100% synthetic. One of the big advantages to synthetic is if an over heat problem ( water pump failure, clogged water intake ) arises it will protect your engine much better then petrol based oils.

“Runability” can definetly be affected by oil, especially in a 2 stroke application whether it is pre mix or oil injected. This oil has to be burned with the gas. If the oil does not burn well, your immediate runability will be affected.

If that oil does not lubricate well while it is in the motor during its short but important lifecycle, then your long term runability will be affected in wear on the motor parts.

Synthetic oils, in my opinion, are superior to petroleum oils because they are made to do what we want them to do…where as petroleum oils have some limitations. Synthetics can be chemically made to mix readily with gas, have a higher shear strength for less wear, withstand higher temps when needed and burn clean and complete in the firing process with less smoke.

Now, as far as brand loyalty, Johnson, Evenrude, and Mercury do not own any oil refineries, so they are not “making” that oil. Don’t feel you HAVE to stick with or use motor brand oil…just like the vast majority of you are not using motorcraft oil filters in your ford vehicles and AC filters in your GM vehicles. Your oil filter is the kidneys to your vehicle motor, but yet we will buy them at discount stores and rapid oil changers, not knowing what they exactly are.

There are several premium 100% synthetic aftermarket oils out on the market that are superior to the engine brand oils, such as Amsoil, Torco, Redline and KLOTZ.

My point is, I agree with most of the comments that oil does affect runability; you should use a good quality oil; and preference would be to a 100% synthetic oil. Include premium aftermarket oils in your choice as these people specialize in making oil for your application.

The Klotz outboard oil is made to give you exactly what you want and need in an outboard oil to protect that investment, whether it is new or old.

Oh, crap…I forgot! Fish bucks are based on number of posts, not number of words! Sorry bout that.

You guys are great ! Thanks for all the info !!

In my OPTI I will stick with their oil because of the DI. But my sleds I chose to go aftermarket, stick with a quality oil, I like synthetic, I would have to say something like Klotz would be a good choice.
