Oil / oil change?

[Badlucky]

What brand oil is everyone using for a 2023 zr4?
What pump are you using to change it?

I can't speak to oil, but I have been using the West Marine "manual oil changer". Well built and works great.

I have the same oil extractor. It works quite well. My only complaint is that the tube isn't long enough to fit to the bottom of the oil pan on my truck.

I use Kirklands oil from Costco. It meets the spec. Used it in my ZR6 and my current ZZ6. As far as extractors I use the Jabsco one. I bought an adaptor that goes on the end of the pump hose and screws onto the end of the oil drain hose. It’s almost zero mess.

We run the "Four Uncles" pump, love it.
But ran the old school end of a drill pump for years, anything was an improvement in the right direction over that.

When it comes to oil ideally, you'd want Pleasure Craft Marine oil - grade 10W-40. For sucking oil out, I'd recommend a jabsco oil pump sucker. You feed the line through the dipstick tube until it bottoms out, hook power/ground to battery and turn pump on and it sucks the oil right out, it is a bit slow but gets the job done. The best sucker though is an oem manual fluid extractor, you'd need to make the proper quick-disconnect fitting for this one though. It plugs right onto the oil drain hose that comes on all PCM motors and is the considerably the proper way to do the job.

I used to do the plastic tube down the dipstick tube for years until I nearly got it stuck. There are stories of this all over the forums which cured me of this method. Unless they've drastically changed how they equip the engines these days you should have a drain tube/hose that goes from your oil pan and is routed to the side of the engine. The hose will look like this....



That end with the metal clasp is typically attached to something on the drivers side of the engine. What I started doing some 15 years ago was attaching my suction pump to that fitting and draining the oil from there. To do this you'll need to go to the hardware store to get a brass fitting that matches what's on the end of the hose and make an adapter to whatever suction pump tube you have. I bought one of these when I first got into inboards some 30 years ago and still have it.


In my case I've purchased probably 3 or 4 different fittings over the years to fit different hose ends as they changed them that look like this....


I then attach a length of rubber fuel line or whatever you have to from the barbed end of the fitting above, to the plastic tube on the extraction pump. That rubber hose has to make a good seal on the extraction tube so choose a fitting that has an end that is the same OD as the extraction tube.

After it's hooked up I turn on the pump and continue on with my winterization steps, remove the oil filter or crack open a beer and enjoy the afternoon. Once you hear that the pump is sucking air, disconnect and move on to whatever else you have going on. This is low drama, simple and effective. You could easily sub in whatever extraction pump you have as long as it has a tube you can match a fitting to.

Oil type/brand is one of those holy war type of things. Ask 30 people and get 30 answers. Nautique recommends 15-40 in my 350 Chevy based engine. I use the full synthetic version of whatever is on sale from Shell or Pennzoil at the time. I just don't put that many hours on my boat per season anymore so I'm not going to get worked up about what might be slightly better. I do only use WIX filters whenever possible across the board in anything I have that has a motor with a filter. I used to use NAPA Gold as well but they recently moved away from using WIX as their vendor and I've heard mixed stories on their quality.
