Ok I saw that some guys buy Rotella brand oil from Walmart. The only thing I could really find was Rotella 5w-40 synthetic. I am not sure what you guys think about synthetic. I was told to run straight 40 weight oil. How much difference is there between 5W-40 and straight 40? Can I use what I bought or do I need a different oil. Motors are 1988 twin 454 crusaders model 350. On the bell housing it advises that the engine is equipped with hydraulic lifters. Thanks guys. |

Brian, I believe Crusader recommends straight weight oils. Sae 40 in the summer, 30 in the winter. Stu |

Brian, check out the explanation in this link. BTW, if you want your oil tested, I highly recommend this company.

I know I am beating a dead horse however, after reading many articles on viscosity of oil I still don't understand how it can hurt to use a multi-grade instead of a straight weight. My understanding is that multi-grade gives your engine proper lubrication at a low temp or at startup. Straight weight gives oil proper lubrication at running temp. If multi-grade gives proper lubrication at both startup/cold and running temp, what is the draw back or why is it not recommended? I guess I am asking what is the drawback to it or what harm can it do to the motor? |

It doesn't hurt at all, all oils eventually break down and the only important thing is that you change it. |

In reading all these postings on oil opinions, it's clear that many have no clue on the technology of oil. Synthetic oil is far superior to any standard oil on that market today! If you are serious about protecting your investment then consider running Amzoil 4 stroke marine oil and Amzoil filters. All this talk about seals will leak etc! is just nonsense. I run the above mentioned oil and change the filter @ 75 hours and oil at 150 hours, even after 150 hours the oil is not black like conventional motor oil. Remember it's not that oil breaks down as much as the filtration is not cleaning the oil or the filtration was poor to begin with. Using cheap oil filters like Fram is not saying much for protecting your investment. At 100 hours I had oil samples done and all was excellent. Both 454s run like a dream and never leak oil or even drop on the dip stick. Remember the engines are always running up hill and your lubrication is the only thing that keeps you from engine damage. My VW and BMW cars run synthetic oil from the factory and the warranty is voided if you do not use the recommended oil, especially on my VW turbo. I have worked around high tech equipment with servo valves etc! for years and it's always about using the best quality oils and premium filtration. You get what you pay for! |

Thanks guys,
I have been swinging wrenches in my garage and working on race cars (circle track) for years now and have been too ignorant to really put any time into what protects the motor (oil). I wanted to thank you all for giving your 2 cents. I am planning an oil change in the next week or so and wanted to make sure I was doing all I could to maximize engine life.
Robert where do you buy your Amzoil products? If possible are they available at any chain stores so everyone can attach their cart to your horse? |

Another recommendation: When I first purchased the boat, the velvet drives made a slight clunking noise when you engaged them. Changed the transmission fluid to Amsoil and they are now quite and very smooth when engaged. |
