Re: SURVEY: BEST TCWIII OB MOTOR OIL?
<br /><br />For guys like me, chosing oil isn't ALL about friction reduction, smokeless running and claims of longer engine life. So...where can I find info that shows synthetic clings better and lasts as long as pet oil during the "off season"? I believe Practical Sailor (unbiased tech org.) did empiricle testing with oils and found pet oil lasted longer than synthetic on parts dipped and exposed to the elements. <br /><br />An OMC warranty rep also told me synthetic left a film (too thin) which wasn't long lasting and corrosion was more prevelant in engines using synthetic that sat for only a month or two between use. That was based on warranty history. To avoid another flame war I won't post(again)what he said about the cost effectiveness of synthetics for the average boater. But it mirrors what Clam says, synthetic oil isn't cost effective when crunching numbers for the whole picture. <br /><br />Engine hrs? 2000+ engine hrs are had with any TCW-III pet oil under commercial use. Many guys get 3000+ hrs. Ask around and see how many home folks really use their recreational motor 2000 hrs to the point of being able to take advantage of longer life from better lube. The answer is NOT many. Ask you own OB expert how many motors die from wear. Same answer. Run synthetic in an OB for other reasons.<br /><br />I'm with the other guys on plug changes. No way and no how do I ever change plugs more than once a year with pet oil. They go 100s of hours without a problem. I've had more plug problems with my 50hp 4 stroke (it eats oem NGKs and doesn't eat the matching Champions). It's either motor problems, mixture or wrong plugs if they are getting fouled often. <br /><br />One last thing. The comparsion of of TWC-III oil as the cheapest mininum is flawed. Oils that don't have the TCW-III certification are the cheap ones in my book (disclaimer: unless the motor mfg specs a non TCW cert oil). Try getting warranty work done when the mfg written specs say to use TCW-III certified oil and you are using something else. Motor books don't spec to use oils that only "claim" to meet or exceed TCW certs. Like I posted already, oil is about more than reducing friction.<br /><br />Peace On Earth!

<br /><br />Maybe I wasn't clear in earlier posts: Amsoil, Samsoil...if it doesn't have the "official" certification specified in the operators handbook I don't use it. That doesn't mean it won't work (hexx, we got long hours with ob engines back in the 50s when straight 30w auto oil was specified). I presume that's the era you post about for many plug changes with pet oil.<br /> <br /><br />Anyway, I was running 100% synthetic in a Johnson 50 ob and mcys (Kawasaki 900, Yamaha 650, Suzukis 125, 175, 750 & 1100) starting back about 1976. I used synthetic in a 38hp 2s Kawasaki powered ultralight plane. My quick count overall is about 14 engines using synthetic. I've consumed cases of the stuff in the past 25 yrs in 2 and 4 stroke engines. I fell of the turnip truck a long time ago. It beats glossy advertising. <br /> <br /><br />Also, I started using synthetic and pet oil in the GAS of 4 strokes back in the mid 80s when the Snapper mower company gave double warranty if you added it in their 4 stroke engine gas (not crankcase). I was blowing engines every couple of years due to high angles of mowing slopes starving oil pickup. That problem stopped 10 yrs ago when I started adding 150:1 synthetic to the gas. I graduated from watermelon school for this one. <br /> <br /><br />
I've run Amsoil in my 40 Merc 2 stroke since I got it(almost), neighbor gave me a case for free! I noticed almost NO smoking, easy starts and better top end speed(3 knots). If you can afford it get synthetic, also winterizes great, here in CA. I don't ever winterize(store in garage).
