Oil Change question

[Tap56]

I recently changed my boat oil. First time changing oil on a boat. I pumped out 6.5 liters using an oil pump from West marine. Put a new oil filter on. I added in 4 liters and let it settle. Checked the oil and it says its full?? Weird. Do I add more or not?

Also, my oil pressure is high while driving? I am assuming this is all related

Thanks for the help!

I hope you haven't discarded the old oil yet. Better be checking for water in it. If 4 liters work out to 5 quarts, about right.

You did fine. Ignore the dipstick reading until you start up and run the engine. Check for oil leak at the filter. Rev it up to 2000 rpm. Observe oil pressure on the helm gauge. Shut her down and clean up your mess while the oil drains back to the oil pan. After 15 minutes or so you can check the oil level on the dipstick. The new filter is empty until the engine runs.

Once you run it the filter will take another ½ bottle of your preferred measurement system. Pressure will be high until the engine warms up. But agree that you need to make sure there wasn't water there. Otherwise fill it using the dip stick

Yeah, something not right. Did you check the level before pulling the old oil out?

If 4 liters work out to 5 quarts, about right.

Well, a 'quart' is a quarter of a gallon (but WHICH gallon?), and a gallon is either 3.78 litres or 4.55 litres (depending on which gallon)... So, yeah, no idea what you're getting at... Why can't we all just use the system YOUR government signed into law 156 years ago and then again 47 years ago!

Chris....don't you still drink a "pint" at your local pub?

I'm in the United States soooooo let's do as us Americans do ! Any way you/he figures it, too much came out.

Probably drinks ½ liter, which is totally lame. Although drinking a liter sounds more appealing than drinking a quart for some reason. Sounds like I'll need to do some market research.

I've been to a few NOLA research sites, been to a few in Abu Dhabi, London, etc. Would need Chris to point out one or two from Perth

I WAS talking about 'Murica... Metric was signed into law in the USA in 1866 and again in 1975, but stubborn yanks refuse to use it, despite it being better, which is why the rest of the world DOES use it. (apart from 2 other third world countries)...

Nope!

Take your pick (or shovel )...

Those oil filters on Most outboards don't even hold a cup(8 or 10 ounces, depending on what country).
As for the extra 2 1/2 liters out of the engine. Did it look like old oil, or did it look like Irish Creme?

 

[Lou C]

are ya liftin' a litre?
agreed I can think in both metric and old English/American but it gets tiresome lol. 19mm=3/4" etc. Funny how lug nuts are still in old school measurements, and most wheel diameters are in inches not MM or CM.

 

[jimmbo]

I was in my teens during the 70s when Canada started the Metric Conversion and I can switch back and forth quite easily. Fluid Measurements were always different to our neighbours to the South. Our cars/trucks always got better fuel economy(mpg) than the same car in the States.

I used to see a few Cars/Trucks with American Plates going 110 mph in a 110 kmph zone. The Local Henry Handcuff usually had them pulled over a few miles down the Road, setting up a get together with the local Crown Prosecutor

Yet Tire Tread Width is in Metric

 

[H20Rat]

Two types of countries in this world. a) Those that have returned men from the moon, and b) those who use metric...


Anyway, oil pressure... entirely normal to see higher pressure after a change. That is a GOOD thing, your old oil had sheared down in grade, new oil is thicker.

Check out the History of the Moon Program, a lot of the Measurements used in Apollo were metric

Same, but what throws me off is those gallons that aren't a gallon. If ya (yanks) are gunna use a different volume, at least give it a different name!

I read this whole thing hoping for a good oil thread battle. I am thoroughly disappointed.
