Oil & Plug Opinions
I can't think of any reason not to use synthetic other than the cost and
this cost is of no consequence in the normal boaters budget. The loads these automotive engines are running under in boat duty is much greater than in the usual car or truck, so use the best oil you can find, i.e. name brand synthetic. That said, most any good oil will do fine as they have in the past, but why not use the best. That's my two cents. Spark plugs? use what they recomend. -- Ron White My boatbuilding website is: www.concentric.net/~knotreel |

Synthetic oil is definitely much better than conventional oil. My boat has
a Volvo engine and I use nothing but synthetic in the engine and in the outdrive. I also use nothing but synthetic in my truck. The way I see it, if you take care of it, it will take care of you.

'97 Chapparal w/ a Volvo-Penta 5.7L Carb w/ SX Outdrive Questions: 1) Volvo pushes synthetics for crankcase and outdrive, yet all the boat places around me (Austin - San Antonio) said to use regular 20w-50 motor oil in crankcase and non-suynthetic in outdrive... Of course they said to change every 100 hours or per season. Experience / Opinions? 2) Any thoughts / experience on spark plugs for this motor??? Thanks! |

I have never used synthetic oil. I have never had an engine failure except one raw water cooled inboard that corroded out after 6 years and 1300 hours in salt water. What would synthetic oil have done for me during all that time except cost a lot of money? |

It would have made your engines last longer than they they did with
conventional oil. I've never had and engine failure either. That's not the point. The point is, do you want your rings and bearings worn out and ready for the junk yard at 150,000 miles or at 500,000 miles. "-v-" wrote in message om... "Frank Taylor, Jr." wrote in message ...

None ever wore out. If you change your oil and filters regularly there is no
real advantage to synthetic oil. "Frank Taylor, Jr." wrote in message ... It would have made your engines last longer than they they did with conventional oil.

Evidently, you have reaped the benefit of taking good care of your vehicles.
Whether you use conventional or synthetic, changing your oil is important. Here are some of the reasons why I think synthetic oil is much better: 1. My own experience - I have been using synthetic oil for about 10 years now. Every vehicle that I have had in that time period has shown minimal wear and lasted several hundreds of thousands of miles (I drive an awful lot) with only minor maintenance. Although it may appear that the parts on your engine have not worn out, they do in fact wear. A car that has driven a hundred thousand miles on conventional oil shows significant loss in compression in the cylinders due to wear on the piston rings whereas a car driven the same distance on synthetic shows much less wear. This does not mean that the car using conventional oil is no longer useful or that it even needs the engine rebuilt. It simply means that the engine is no longer quite as efficient and powerful as is used to be. My last car had so little engine wear after 300,000 miles that my mechanic said that it looked more like it only had 20,000 miles on it. He attributed it to the fact that I use synthetic oil. Three years ago, I gave it to my brother-in-law with 328,000 miles on it. He is still driving it. And get this - It's not an expensive car, it's a Dodge Shadow ES. I also notice that my engine runs a lot smoother with synthetic oil. Maybe that does or does not mean anything when it comes to how long the engine will last but it sure sounds better. 2. Planes - Yep, planes. This is where synthetic oil actually first started being used - - - in airplane engines. Conventional oil could not hack the harsh environment of some aircraft engines so synthetic oil was developed for use in aircraft. I have had a chance to talk to some of the engineers at Lockheed and one of them gave me a real good lesson in why synthetic oil was so much better. He convinced me. 3. Test after test after test - There have been numerous independent test that have shown time and time again that synthetic oil is superior. If you want some more info on why it is better, you can go to http://www.dirtroad.com/oil2.htm. 4. If conventional oil was just as good as synthetic, why do most NASCAR teams use synthetic and why do some auto manufacturers put synthetic oil in some of their new performance cars and require it for their warranties to remain valid? The fact is, that synthetic oils are better. Yes, they are more expensive but they are also better. "-v-" wrote in message om... None ever wore out.
