Outboard Engine Oil

Re: Outboard Engine Oil

Check SuperTech and the expensive "brand name" oils and see who really makes them. See if any are listed on the bottle as "meets TC-W3 minimums". All will say "Meets or exceeds all. . .".

Synthetics and blends have a legitimate claim to be better for the engine and the environment. I guess that makes them eligible to charge more.

I have no intention of paying for advertizing, marketing and merchandising costs that inflate the price with no proven superiority of the product.

Sums my thoughts on the subject--

I use Alisyn full synthetic in all of my engines. We use it for 10,000 RPM race engines and never had an oil-related failure, so it's good enough for everything I run. And it costs less than brand name oils too.

Re: Outboard Engine Oil

I've read strong opinions by both sides, so I'd like a consensus on whether or not it is safe to use any TCW3 rated outboard oil.

If your outboard motor manufacturer stipulates that oil rated TCW3 is the requirement for engine, then any TCW3 rated oil will be perfectly fine to use.

You may however be required to decarb a bit less if a TCW3 synthetic oil is used.

Re: Outboard Engine Oil

For 6 years I used the cheapest oil I could find to feed my Merc 115 hp 6 cylinder premix. (did use a lot of oil indeed) It never blinked an eye on me. Nowadays I use synthetic with smaller OB's for my own satisfaction and to please our planet. Nevertheless I do feel ANY 2 strokes oil would do the job fine.

Re: Outboard Engine Oil

TC-W3 is a designation that is placed on oil to say that it "meets or exceeds" the recommendations of the manufacturer. However, they are not all the same. Does that mean they do not all lube well, no, but there are some differences.

When I got my boat with a '85 Dt115 Suzuki, I ran the Supertech. I felt it lubed well, but it did smoke quite a bit at idle speed. When I switched to YamaLube, the low speed smoking was almost gone...

The differences is the aditives and detergents that are put in the oil. I think the more expensive name brands may use better additaives, or monitor the mixes to closer tollerances. Either way, TC-W3 will provide the lubrication needed, but cheaper oils may leave other deposits that will need to be cleaned out more often, requiring a little more routine maint...

Synthetics are much better for may reasons, however, not neccessarily with in everyones budget...

Re: Outboard Engine Oil

I use about 65 gallons of oil per year in 4 different engines all running 50:1. I have never had a problem due to using whatever is the cheapest twc3 oil. The engines that I maintain are run hard about 5 hours per day 6 days a week 8 months of the year. The only things I change are spark plugs and impellers.
