455 oil
« on: June 02, 2011, 10:15:25 PM »
I just had my 455 rebuilt. It is .040 Mostly stock other then that. I have run 40w in the past, and was curious what everyone thought about what brand and weight to run.

Your going to get several different answers to that question, and most will work without any problems.

I use Chevron Delo 15w/40 diesel oil in my BBC because they haven't regulated the zinc out of it yet.

If you haven't done the cam break-in yet, be sure to use a premium break-in oil or add an additive like the Comp Cams stuff

Totally loaded question.....

Really without knowing how it was prepared and machined all suggestions are just guesses.

How you run it, what the pressure and temperatures are, how tight the tolerances are among a treasure trove of other good stuff all point to the right oil...

Typically can't miss with a high zinc racing oil in a multi viscosity, a good start might be a 20W-40 racing oil, it will be difficult to find, but the low viscosity differential will mean fewer polymers to make the multi vis formula...

You want to look at the viscosity index, should be over 120, this number is the property of how well the oil stays at its rated viscosity at higher temperature swings....The higher the better....

Brands....I don't care what the label says, the facts about the oil can be found.....Just stay away from the "snake oil, feel good, liquid ball bearing bullshit and do the homework...

Good luck

In the jet tech section of Hot Boat, someone asked the same question to Greg Shoemaker. He prefered a straight 40wt. I have heard the same from some of my mechanic friends.
You can do a search here and on Performance Boats jet section and find a few threads about oil preferences in jet boats.
Boat motors usually run looser tolerances, higher RPMs than cars, so I think that is the reason for a thicker oil.

Although I really respect Greg Shoemaker, in this particular case, "better safe then sorry" applies, I am not sure any of us on here know how the motor was built....

Cold SAE 40 is hard as hell to pump and wont do squat until it warms up.... ;)  The multi Vis can save you some grief and make slop count the same as skill..... :sly:

It all depends on personal choice and the particular needs of your motor. I'm not well versed when it comes to the 455 but I do know that the oiling system in those motors can be a bit problematic. Everyone I know that owns a boat runs a bbc including myself. We all use 20w50 One guy runs Castrol GTX. Another guy runs Valvoline VR1. And yet another guy I know runs the Pep Boys house brand. I use Royal Purple and my motor seems to be okay with it. At my shop we stock 15w40 for Diesel and very high mielage engines only.

I would run Valvoline VR1 20/50. I would definitely stay away from so called "diesel" motor oils, they're not formulated to spin 4K+ all day, they have some crazy detergent packages and will aerate (foam) in the pan. The 455 is a special beast of it's own when it comes to oiling. Go with a GOOD 20/50

Taco'd "a person or people that show up with one lake lice and a family of 50 and cram 3 people at a time on it with no disregard to boating rules or ethics. Usualy crap in toilets and throw shit paper in trash cans. Hang out at the boat ramp like its a swimming hole. Have zero insurance on anything they own and dont give two shits less about your property."
