I use mobile One synthetic straight 40 weight number of quarts off hand I can't remember. I want to say 6 including filter. I put five in, then turn the motor over without letting it start. I then wait 10 minutes check oil level and add as needed. ------------- |

I'm not sure you want to put synthetic in an 81. My 454 in my Supra I just put straight 40w. You're probably going to get 4-5 quarts out of it depending on whether you pump it out or drain it. Put back in whatever you took out.
Here's a post that discusses mob1 oil in older engines... http://www.correctcraftfan.com/forum/forum_posts.asp?TID=4510&KW=lifter - sudden oil pressure loss ------------- Mullet Free since 93 http://www.correctcraftfan.com/diaries/details.asp?ID=717&sort=&pagenum=1&yrstart=1991&yrend=1995 - 95 Sport |

don't use syn oil in an old motor unless you realy want a new motor in the near future. Should be 5 qt with filter start there and check level add as needed use 10w40 or 20w-50 valoline, penzoil or castrol. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

When I first bought my Dominque ten years ago, I used Mobil 1 10 w 30 and found oil leaks that I didn't have before. I switched to Castrol GTX 20w50 and all the leaks are gone. I run 35lbs. pressure at 600rpm. I have not had any problems. I use synthetic oil in my Silverado and at 100k, still runs strong. I believe the rope type seals and cork gaskets in the older Big Blocks are not desinged for the newer type oils. As far as engine damage goes, It's not the type of oil, it is the lack of oil, that causes damage. Put in 5 quarts of oil, and check the level when the boat is in the water.{CC recomends this}.Have been an auto tech. for 32 years{not a rookie}.

Not any more, do some research on cam failures from lack of zinc-d, ZDDP, etc. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

| About a year ago I switched Rotella Diesel Engine oil 15W40 in my boat ('84 351W). The only thing I'noticed is the oil get dark faster and I seem to be using more oil. I'm thinking of changing to SAE 30 at the next oil change (Still Rotella). |

| Yes, Shell's heavy duty engine oil. I don't know if I'm gainning anything or not by using Diesel Engine oil. I can't imagine it hurts anything. |

well somethings the heavier oils are a little tough on the oil pump and starter when cold on older engines it's propably a good call on a fresh rebuild I would use 10w40,, 20w50 valvoline or castrol racing oil is what I use in mine. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |
