Oil change help

The Land of High Taxes-Illinois.
 
What type of oil do the 1.8s take?
 
What type of oil do the 1.8s take?

I use Yamaha's Yamalube in their kits. I refuse to pay for the dealers service but by buying the supplies from them I still have a record of Yamaha parts and write the current hours on the receipt then file it.
 
@Julian here is a screenshot from the owners manual for a 2014. I used 10w-40 on my jet ski. As I noticed a few members using it on here. Hope it helps ya

@Julian I think you would be fine using 10w-30. You may want to check your owners manual, but on my 2011 the manual lists multiple types of engine oil. From what I understand, the 30/40 is the spec for viscosity at 100*C. A -30 oil will be thinner at 100*C than a -40. Full disclosure, I'm not a mechanic and I have no idea how much "thinner" the oil will be or if it is of concern.

Here is the specification for the 1.8L from my 2011 manual showing the recommended oils.

10W 30 is all that is listed in my 2008 AR230 manual.
 
Hey guys, I did my first self performed oil change this weekend to start getting the boat ready for storage. The last oil change was the 10 hour service that I had the dealer do. I was a little surprised because I got a full 4.2 quarts out of the starboard engine and about 4 out of the port. I just used a west marine manual pump through the dipstick tube. Would you be worried that maybe it was overfilled before? throughout the summer the oil was at the top fill line. I added about 3.75 quarts to each engine and will get it on the water and check levels with warm engines next chance I get. It's been tough to get on the water lately because we have a 7 week old baby boy at home.
 
I figured I would throw in my 2 cents on oil changes. I used to use Mobil1 like in my car; but after all of the debates, I called Yamaha Corporate about the best oil to use for these high revving engines. I was refered to their technical department. What I was told not to use "car oil" and that a full synthetic oil made for marine applications with 4-W FC-W rating was best and would increase performance and engine life. FC-W lubricants have demonstrated the necessary performance, additives, and quality needed in high performance four-stroke marine engines. Of course they recommend Yamalube and Yamaha filter, unless you can't find that, then another full synthetic marine oil and high performance filter could be substituted. Well I did a lot of research and calling around and I came to the conclusion that Royal Purple HPM (high performance marine) was the best stuff out there imo; so that is what I use. For a filter, I always use K&N, but have considered using Royal Purples filter; however, the Yamaha filter is top notch and made similar to those in Mercedes, so I may go to one of them. I know there is a lot of debate on full synthetic vs dino juce; but full synthetic wins in every case except price. Jeggs usually has the best price. You can check out a test at
. I swiched to RP in all my vechicles now.
Now for sucking the old oil out....I first used a hand pump; but didn't like the results. I didn't want to spend the bucks for a high dollar extractor, so I made one that performs better than any I have seen. It ain't pretty but here it is:

I used a strong bucket and a lid, clear plastic tubing and pex as the wand. On the other end I attached the tubing to a shopvac hose via an adapter. in the lid I drilled 2 holes and inserted 2 pex lines that I attached the plastic hoses to, with the in line longer than the out line, to keep oil in the bucket and not in the shopvac...notice no oil in the out line. I actually have also added a smaller flexible line to the end of the probe to reach more areas. This set-up really sucks and I found the bucket needs to be strong...I used a chlorine bucket. Note: a Home Depot bucket WILL NOT work as you can see:

Like I said...it really sucks...lol. Hope this helps.
 
@*DMZ* I think about those "testing" videos, not everything is what it seems, I'm sure I don't need to tell you that -- LOL. Royal purple has recently changed owners and the formula has changed, that is not always for the best. Same with filters -- Yamaha oil filter you are referring to (w/mercedes like medium) is no longer available/hard to get, it used to be made in Japan, the new ones are made in Thailand and have regular media, not the fleece like stuff.
I think Yamalube remains a safe bet. When perusing greenhulk threads, it seems about evenly split between yamaha oil and amsoil marine in terms of most popular choices by hardcore members there.

I know some videos are very misleading. I just used it to give a visual. Here is one obviously not done by RP comparing it to Amsoil
I have seen the same test by multiple people; that was just the best done one. All of the results were similar. And yes RP did change owners about 5 years ago. I think Calumet bought them. As for the formula change, I was aware of that too; but it is in their passenger car line and had to be done to meet API requirements. Last I knew Amsoil was not API. It has to do with reduction of the amount their Synerlec additive to meet API requirements for Automobiles; but the marine and performance oils are still the same. I didn't know Yamaha changed their filters either, guess I won't try them till I learn more. I do know that unlike many think, Yamaha does not manufacture any of their lubricants or filters. I think Mobil1, and Royal Purple filters are made to spec by Champion with the big difference being no cellulose in the RP filters....K&N was manufactured in the USA, but they moved to Mexico and although the design hasn't changed, tolerances for the hole and threads seem to be not as tight now. Another thing that many may not know is that there are a ton of counterfeits out there on ebay and amazon....same with plugs. I just ry to get what I think is the best...and everyone has their opinion. I usually say to use performance filters and a fully synthetic marine grade oil and you should be ok.
