Author Topic:   Oil Additives?

I've got 85 hours on my Yamaha 50 hp four stroke since I repowered in March. The oil was changed at 20 hours during my post break-in tune-up, and I changed it (Yamalube 10-30) at 75 hours. I've never used oil treatments/additives in my cars, but then again I have never let a car idle for several hours at a time, like I do, in effect, with my Yami while trolling.

What's your feeling about the efficacy of oil additives, folks?

Hi, Elaelap.

I would let well enough alone as long as you are using a premium oil.

I use Mobil 1 in my Suzuki. Suzuki told me not to add extra "snake oil".

Like JB sez, "no snake-oil additives".
Use any engine oil that meets the SAE and API specifications recommended by Yamaha.

That's my gut, too. But what about some of you other motorheads--Sal, Bigshot, Leone, et al.?

Yamaha markets a gas additive, Yamaha Ring Free, which is claims to prevent carbon build-up and improve lubricity and mileage. It seems similar to the Chevron Techron gas additive for automobile engines.

Hey all...some of you may know this others I am sure do not. I work for SAE...yes the guys on the oil can. (you can tell I'm old, I still say oil "can", yes youngsters they were metal cans at one time).

Anyway SAE does testing on all oils, hence the can indicating SAE10W-30, 5W-30 etc. What SAE does not do is test additives. We do this because, although there is some truth to the claims of increased mileage, longer life, increased standards exist in the oil additive industry.

Although I have used certain additives in my 200,000 mile Explorer...I figured at that mileage, little damage could be done. If I have a well maintained and good running engine I would reccomend not adding what is basically foreign materials.

I have tried snake oil from time to time, but one never knows the reluts unless something happens to prove the point. My only experience on that end is with KLOTZ 2cycle synthetic racing oil. I was using it in an injected 125cc Yamaha and the bike sucked a seal on the crankcase and the RPM's went wild and pegged the tach at 12,000 RPM before I could get the gas shut off and it ran itself out of gas. It did not siezed or hole the piston as one would have expected. I too it to the bike shop and the owner (who raced motorcycles) told me it was the KLOTZ oil that kept it from seizing up and ruining the engine. About the only thing I use klotz in now is my Husky chainsaw because thet turn up a few RPMS when running wide open for long periods of time. Just my 2 cents
