Confusion over engine oils
At one time I asked Bill Grannis if he had a recommendation on which oil I
should use in my new Yamaha 4 stroke. He responded with information on TC-W3 approved oils which are used in a 2-stroke. He quickly realized the confusion and provided another answer applicable to four stroke engines. Please note that neither Bill nor I recommended using a TC-W3 oil in a four stroke engine. Here is part of his most informative answer: ***************************************** On 4-stroke oils, there is a fairly new certification system endorsed by the oil blenders and the 4-stroke manufacturers, called "four-stroke, water-cooled" or FC-W. Because an outboard may run in sal****er, sit unused for long periods of time, and runs high rpms for hours on end unlike a car motor, the industry wanted a spec for approved outboard oils. New owners manuals now state what oil grades to use and say an FC-W certified oil if you don't use an OEM lubricant. If you are into synthetics, surprisingly the Amsoil 4-stroke oil is FC-W approved unlike their 2-stroke oils which are not TC-W3 approved. Here is more info on the FC-W lubes: http://nmma.org/certification/programs/oils/fc-w.asp ********************************************** The link provides some alternatives for those buying oil for four stroke marine engines. Thanks again to Bill Grannis! -- John *H* |
