Re: oil oil oil...
OK, I made the crack about listening to the voices in your head, but here's my take. I use the same care and layman's criteria that I use with my cars (some new, expensive, high tech, some old and low tech):<br /><br />Premise #1: Proper use of oil is more important than choice of oil (e.g. for cars - regular changes using correct weight; for outboards, proper mixing using certified TCW3).<br /><br />Given this, I would never worry about using "Brand X" el-cheapo oil if I had to, but don't make a regular habit of it - for my cars or boats. Why? dunno.<br /><br />I buy "known brands" of oil for my car based on convenience and price, but I can't emphasize this enough, never ever skimp on regular changes. E.g., with my cars, I use whatever motor oil my normal oil change guy uses - a "national brand" like Pennzoil, Quakerstate, Valvoline, Havoline, Castrol, Exxon, etc. etc. For my boat, I buy either bulk OEM (Johnnyrude or Merc) if I happen to be in the neighborhood of the boat store - get it for around $14 per gallon. Often though, since it's much more convenient, I buy Castrol or other name brand TCW3 by the case in qts. or in gallons, because my local favorite hardware and big box stores always has a good price on it whch works out to around $10-$15 per gallon. I haven't tried the cheapest products at Walmart yet, but will probably run a gallon this summer just for fun. <br /><br />But, I can't really figure out why I'd buy the cheapest oil for eithr my car or outboard - because I am not broke and the cost savings is so insignificant. There were times in my life where I absolutely would buy the cheapest oil because the small price difference was significant and I don't think that was necessarily a bad thing. <br /><br />For example, back then, if I saved $5 on an oil change, that would buy a case of beer which I otherwise couldn't afford! Nowadays, I'm so rich I can buy expensive oil AND a case of beer (sometimes even expensive beer!).<br /><br />Mostly, when I need oil, I listen to the little voices in my head and don't worry about the miniscule percentage in seasonal cost for expensive vs. cheap. Hell, I NEVER price shop for gasoline, but buy based on location and ease of getting my boat/trailer to the pump - and that's a much more important factor!
