what's your oil preference

[_kq_]

Just curious on what kind of oil some of you are running in your boats and your thought and opinions on it, the reason I ask is because the guy I recently bought a boat from was running straight 30 weight valvoline and I'm not sure if I want to continue that. I don't know everything about oil, but running a 10/30 or 10/40 sounds better for the motor than straight 30. Constructive criticism welcome!

I'm running a stock bbc 454 in a jet boat with 380hr on it

 

[Uncle Dave]

In my V10 Viper mill Mobil 1 0W-40. Because Ilmor says so.

Not sure what Alexis going to recommend on my new 588.



IN case it comes up - Napa Gold , and Wix.

stay with straight 30w

 

[Uncle Dave]

Curious to hear the rationale on running a straight grade oil.

KQ - If you want to learn about oil a tremendous resource is called "bob is the oil guy/"

They have a good oil 101 class thats mostly right.

They have tribologists and factories weigh in from time to time.

Not into straight weight either. 20/50 is what I would run.

 

[rivrrts429]

You're fine with a straight 30wt. Unless you're running in really cold temps the straight 30 will be fine.

I'm guessing you're not running an oil cooler on the jet boat? Really weird dynamics on jets with cool river water on an open loop system but hot motor oil. I've ran straight wt's in my jet boats for years with no issues.

Stick with what the previous owner ran for 300+ hours.

Delo 400, 15W40
Higher zinc content than most.
Higher shear than most.

Valvoline VR1 40 wt. TT 565 c.i. v drive

 

[BUSTI]

I like Vr1 but Teague recommends Kendall 50.

Currently boat is running Lucas sae (non synthetic) high zinc 10-40. After this season it will be switched over to full synthetic Lucas 20-50 high zinc.

Motor is brand new and first 10 hours ran Lucas break in oil. First season non synthetic, and will run synthetic from there on out.

With today's oil technology.....there is NO reason not to run a multi viscosity oil. Running straight weight oils is not the best route. Many engine manufacturers are now going to 0w- multi viscosity oils.

In the boat it was common to run "diesel" oils due to having higher zinc levels. But many oil manufacturers offer high zinc products that will perform better in a marine application.

What is beneficial about running the non synthetic the first season? With the break in oil for the first couple of heat cycles the rings should have seated already.

Brian at B&D said that's what he wanted so that's what I did. Lol. It's his motor and his warranty.

 

[OCMerrill]

I have Lucas in everything now. I know a guy that has a cousin......

0WXX oil is recommended by manufacturers for emissions and efficiency, there is no other reason. We are not really worried about either of those in a boat application.

For custom built or high HP engines you should not run 0Wanything in a car or a boat. I'd say stay away from 5Wanything as well personally.

I run Amsoil 15W40 in my stock 6.2 Merc. I may go Lucas next year.

Illmore is running quite a few 0w- specs on their line of motors.

Last time I was at Morgan Lucas racing. They were talking. About how everything they are doing now is with 0w oils. You will see it becoming more and more prevalent in high horsepower applications

Mind you this is info from people way way way above my pay grade and knowledge level when it comes to oil. Half the time when they're talking to me I just nod my head and act like I understand what they're telling me. LOL

 

[BDMar]

It's virtually impossible to recommend what weight oil to use with out knowing what the rod and main bearing clearances are. Bill is running the weight and oil type I recommended because of the bearing clearances I set up. The petroleum oil for the first season is to give the rings lots of run time to seat before switching to synthetic.
A stock 454 in a jet, to be safe, I would run 15W-40. It could be a stock GM automotive crate engine. In that case the clearances will be a little tighter and the 15W-40 would still be ok.
The Lucas 10W-40 that Bill is running would be a great choice.

I'm running 20/50 Lucas semi Syn Straight Racing Oil in my Boostpower 540.

I run amsoil 20/50 z-rod

 

[djunkie]

I've been running the Lucas marine 20/50 in my engine since new as recommended by my engine builder.

If the engines clearances are built and set up for it, and set up to run the specific oil temp required to run it that weight of oil, absolutely.

Would I run it in a run of the mill medium or high perf SBC or BBC rebuild, or OE merc build, especially something I bought used, No way. Not without oil temp data at least.

Is the Iilmor stuff LS based now? Those guys are running it because it frees up a bit of power, but it really comes down to desired oil temp and bearing clearances, etc. Those setups are above most of our pay grades too, mine certainly . If they told me to run it in their engine, I would not question it.

 

[Ballyhoo]

Right after rebuild it was Kendall 40W until they stopped making the green oil. Now its Brad Penn 40W. Oil choices are per engine builder - Carson Brummett

I really never heard of Kendal until Savage Marine put it in my boat. Sounds like good stuff from what I've read.

 

[BSP14]

Kendall 20W 50 in my EFI 500; as Hallett used in it.

 

[Crazyhippy]

Penzoil tcw-3... change it with every tank of fuel.

 

[Squirtsfar]

I run Kendal W40 in my Jett Bote. But I don't know shit so consider that when you make your choice...

Your wasting perfectly good oil. Change it when you adjust the valves. :thumbsup

 

[Gasnsuntanlotion]

That's what Teague put in my modified 525.

But I'm goin back to mer semi synthetic 25-40

 

[spaniard]

You guys that are running the VR1 run into any issues by now? How has it held up?
I'm considering running vr1 straight 40 on a stock 502 big block,

This season I ran VR1 straight 40 on a 1,000 horse blower motor. No issues but I change it every trip.

Same exact oil I run in my 1978 Harley shovelhead with a whopping 45 horse power =)
