Re: Using Synthetic oil in newer outboards ?

I run Mobil 1, I had e-mailed them when I purchased my new motor to ask them what they recommend for a break in time. The response was that you do not need to break a motor in with dino oil you can run synthetic from the first start. To back there point they said that corvetts, porsche, bmw ect all come from the factory with Mobil 1. ;)

You can use Synthetics from the git-go. Amsoil is the best synthetic oil made.

Re: Using Synthetic oil in newer outboards ?

If a Synthetic oil is put in a new eng,under warranty an you have a parts failure or blow up a eng,would this mayby bring up the bad 4 letter word.VOID warranty?? I no Mobil 1 puts its synthetic oil in new Corvetts, BMWs, Porsche, but would this hold up for outboard motors under warranty??

I run Mobil 1 in everything i own. Independent tests show its the worlds best, Amsoil is usually 2nd. I run it in a 40hp 2003 Honda.

I wouldn't run Scamsoil in my roller skates much less an outboard.

Re: Using Synthetic oil in newer outboards ?

Be careful of independent oil companies that claim miracles by using their oils.<br /><br />All my Yamaha 4-stroke manuals specify an API grade oil. These are oils that are certified by the American Petroleum Institution, and carry the "Starburst" symbol. You can go to API's website and find which oils are certified and licensed. Make sure to look for the specific viscosity and rating specification (Example: 10W-30 SE, SF, SG, SH, SJ).<br /><br /> http://eolcs.api.org/DisplayCompanyNames.asp <br /><br />Many oils, like Amsoil, claim their oils meets the API specification. But that is their own claim, based on their own testing results, as these oils are not certified by the API as such. You just have to take their word for it. :eek: <br /><br />For example, Amsoil has specific oils designed for 4-stroke outboards. They claim these oils meet the API specification. But none of them are API certified. There are only a handfull of other Amsoil engine oils actually certified by the API, and some of them are blended dino/synthetic oils, not 100% synthetic. None of them are specific outboard marine use oils.<br /><br />If engine failure could be attributed to the oil, then using a non-API certified oil could void your warranty. BTW, there are brands of 100% synthetic oil (other than Amsoil) that are API licensed.<br /><br />You really can't go wrong using the outboard manufacturer's brand oil. They will have synthetics too. It may cost a few dollars more, but you know it is specifically designed for your engine, and it ensures your warranty. Not to mention peace-of-mind.<br /><br />IMO, dino oils have everything in them that your outboard engine needs, and they have been proven to maintain engine wear for thousands of hours. I would begin using synthetics only after the first few changes of dino to ensure good ring seating and "wear in" of mating parts. <br /><br />I use both synthetic and dino in several different outboards. I haven't really noticed any major differences except that the synthetics cost more. Some of my outboards actually perform better and live longer on dino oils. And the oil still needs to be changed as frequent due to contamination. :D

Re: Using Synthetic oil in newer outboards ?

Mobil1 is a great synthetic. Mercedes uses it on thier new motors. The motors they are using it on have reduced tension chromium rings against silicon/bronze/aluminium cylinder bores. Same as most BMW's. Ring seating is almost automatic in only 75 miles. <br /><br />The issue is proper ring seating against a cast iron cylinder. This is much more of a process.<br />The Redline synthetic oil that I use in my outboard states right on the container, " not for use during break in of engine, allow 3,000 miles."<br />I allowed 20 hrs. on my outboard before I started using synthetic.<br /><br />The purpose of break in is to wear off the rough edges, microscopic burrs and to start an even wear pattern. Many are using synthetic for its superior friction reducing capabilities. With that thought in mind, wouldn't it logically hasten hamper or otherwise delay the break in process?<br />Since we're not using the same type alloys in our outboards that the previously mentioned autos are. It certainly wouldn't hurt getting your rings seated with dino oil properly then getting the reduced wear and greater flow that the synthetic of your choice provides. ;)

Re: Using Synthetic oil in newer outboards ?

billy-bobby the advantages are the oil will not break down like conventional oil, wont sludge its lubricity(is that a word?)is vastly superior.And if you have an oil pummp failure it could make all the difference.Running Mobil 1 will not affect warranties at all.The disadvantage of course is cost but im willing to pay it.Also you should still change the oil at recommended intervals in outboards unlike say an automobile, which can raise the interval with synthetics.

Re: Using Synthetic oil in newer outboards ?

I had a personal experience that helped me switch to Mobil 1 synthetic.<br /><br />The first year I had my 40 4-stroke Yamaha, the weather got pretty cold in Eastern Washington (duck-hunting). The motor ran extremely rough and took 30 minutes to warm up when it was 8 degrees, and would not start at all at zero degrees.<br /><br />After studying the properties of synthetics and dino oil, there is a huge difference in "pour points". Mobil 1 has a pour point 20 to 30 degrees lower than most 10-40 dino oils. I've had no problems with cold weather since, using Mobil 1!

And I thought I had guts :eek: :eek: :p <br /><br />But then, only three posts, what do I expect. :D <br /><br />Welcome aboard fellow Amsoil user. :D <br /><br />If you look really, really, really close, right below the cowling on the merc in the avitar, there is an Amsoil decal there behind the spray, yes, I know, Its hard to see, but its there :D :D

Re: Using Synthetic oil in newer outboards ?

AMSOIL is one of Merc's biggest pet peeves. I wouldn't use it on anything under warranty. In fact I wouldn't advise Anybody to use any brand other than the manufacturer's own during the warranty period. They Can't deny warranty if you use Their products. After that you're on your own and you can believe anything you read if you really want to. It's in Black and White, so it must be true, right? :rolleyes: You won't have to worry about who's going to pay to replace a blown powerhead under warranty (Merc or Brand X Oil Co.) because there isn't anymore warranty.<br /><br />MerCruiser's HiPerf gearlube IS synthetic. We put it in every Merc/Mariner product from the smallest outboards to the biggest outdrives. Never Ever had a problem with it and I've probably filled a good 10,000 gearcases with it by now.<br /><br />The biggest advantage of synthetics is their broad temperature range. They stay thin at cold temps and tolerate high temps better without breaking down. Good for cars in Alaska, or the Mojave. But you aren't going to be operating a boat in sub-zero weather unless you want to freeze in place out in the middle of some lake somewhere. Or if your outboard is running really hot, you have much bigger issues than what oil is in there. That said, would I use synthetic in My outboard? Yup. At the Apporpriate time. ;)

Re: Using Synthetic oil in newer outboards ?

1) Sythetics lubricate better than conventional <br /> oils.<br /><br />2) Synthetics lubricate better at start up. <br /><br />3) Mobile one exceeds the API ratings required <br /> by the Yamaha manual.<br /><br />4) mobile one will not void your warrenty, I <br /> called Yamaha directly on this issue. Plus <br /> Mobil 1 would stand behind you if it ever <br /> became an issue. It is their livelyhood.<br /><br /><br />5) I did not use it during breakin because some wear in the very beginning is nessesary. Ever look at your oil after the first oil change. lots of metal in there.<br /><br />Fork, I have to respectufully disagree with you besed on my prsonal experience. I have a Bonneville that has gotten regualr doses of mobile one. It has nearly 240,000 and the engine is still very tight. <br /><br />I use it in eveything. If a $ 100,000 mercedes reccomends it for their cars i think Yamaha and Honda 4 strokes can handle it.<br /><br /><br />Final point. Do you think Yamaha has its own lab where it has discovered the best lubricant out there and manaufactures it in a confidential plant ? <br /><br />Their Yamahalube has a specfic ingredient that no other oild have ?<br /><br />Their oils are constructed out to some of the same companies whose products we are saying voids the warrenties.<br /><br />No intention of insulting anyone here.<br /><br />Kid
