synthetic oil

[fire-engine]

hi gents, would like to know if 100% synthetic oil should be run at 50:1 or 80:1 or 100:1 in my 1988 evinrude 120 looper,vro is disconected i do pre mix, and if i do run at 50:1 would i see less smoke, than i do now w/johnny rude oil or would i have to run at 100:1 thanks

Re: synthetic oil

Use the mixing instuctions for the oil you use. Most will be 50:1, Some, Amsoils new saber outboard oil is to be mixed at 100:1, I would mix it at 80:1 if its used on a bass Boat where you are running WOT near all the time. Other than that 100:1 is fine as it is formulated to run at that ratio.<br /><br />Synthetic are a good move, even though they cost more, you get more in that you do not foul plugs, you have much less smoke, and you do not have the carbon issues you do with regular TCW-3, and actually just better overall performance, If you switch, you wont be sorry you did!

Re: synthetic oil

Just to clarify, DO NOT use any oil OTHER than Amsoil Saber at 100:1...It's designed to be used at that ratio.

Lubedude, How are you.Do synthetics realy diminsh carbon deposits?Or does this happenn because or the leaner mix.<br />DHP

Re: synthetic oil

Thanks for asking, Actually been feeling pretty good. I think once I get my merc 150 runnung good again Ill feel like a new man. I just hate it when there is something hanging over me like that! <br /><br />The synthetics just burn cleaner, thus, less smoke and less carbon deposits!

Re: synthetic oil

Hey Lubedude, while the topic is up, I know the synthetics burn cleaner and I now they are supposed to protect as well or better than reg. oil, but do they really. I'm not trying to start a whole oil thing here, but just really want to know the real deal, if they do protect better and burn cleaner I will deffinetely pay more for them. I have twin 200 Johnsons and they drink oil(and fuel), I usually use reg. oil because it kills my wallet to fill up twin 5 gallon oil tanks with synthetic, but if it is really worth it I will consider it. I love these motors and want them to have the best protection, but if I can it get from reg. oil, I have no problem decarbing once a year and dealing with the smoke(which is a hell of alot by the way). Thanks alot, Mike.

Re: synthetic oil

I fully understand your situation! If the synthetics were, JUST AS GOOD, I wouldnt bother people with using them, Honestly, there is no comparison at all. There isnt one thing that conventional oil will do better than a high quality synthetic, (other than be cheaper) and they really arent in the long run. No need for decarbing, and spark plug replace ment will be much less. There are indeed differences in synthetics also! I beleive that this is what I would like to see you do, just for the people on this forum! Run your tanks down and buy two gallons of the 100% synthetic of your choice. If you can find a local Amsoil dealer, buy the HP Injector oil, Its the best there is and not much more than the Penzoil! Suck out as much of the old oil as you can with a turky baster or something of the sort and put a gallon in each oil tank. Dont worry about a little of the old oil being left, it will mix fine, Start your engines and slowly motor out to the open water and then just run the engines at a moderate speed for a few minutes, 5-10. This allows the synthetic to wash through the engine, then go ahead and hit it and run at whatever speed you normally run, Check out your WOT RPMs and compare. Im sure you know what they run now. I wouldnt be surprised to see a 100-200 RPM increase with the synthetic! Then when you get back to the dock, the next time you start your engines, notice how much they smoke (or dont smoke) compared to before and let us know!<br /><br />If you like what you see, as much oil as you use, you could become a prefured customer and by the Amsoil at wholesale prices and save yourself some serious change.

Re: synthetic oil

Lubedude,<br /><br />I have been reading your posts and have pretty much figured to change to a synthetic. For the most part I see you talk about Amsoil. What other brands would you reccomend to put in outboards??? I've been doing some reading on Royal Purple. This synthetic has me sold in automotive engines as my vehicles run better and the oil changes are prolonged. Any suggestions?? By the way, I run a Suzuki DT 150.

Re: synthetic oil

If you have no dealer around and do not want to mail order, the penzoil products are fine, if you are going to change, go all the way to full synthetic. I have no experience with the royal purple and do not know there base stock, Im sure it is probably a fine oil. You will be hard pressed to do better than the Amsoil line.<br /><br />As far as the Royal purple in you car, my personal opinion is that mobil1 would probably be a better choice if you do not want extended drains, Allthough you can strech to 7,500 miles. and Amsoil if you want to stretch your changes out farther than that which makes it cheeper in the long run! Royal purple is spending a lot of money on advertising and I do not beleive it to be any better at all. Just a lot of hype. (Its certainly not going to hurt anything though. Stick with the top two, Amsoil and Mobil1! In that order.

Re: synthetic oil

Thanks alot Lubedude, I think I will deffinetely change to the synthetic, as well as in my gearcases. I already use synthetics in my truck and car, in the engine, tranny, differentials and transfer case. I pretty much figured it was better for the engines and have seen it first hand smoke less, but the price always held me back. If you could tell me a good place to buy it in wholesale in bulk, I would deffinetely mail order it, as I usually go through alot of oil in the 250+ hours that I run a season and it would probably save me some money that way. Thanks again, I appreciate the help and knowledge.

Re: synthetic oil

mmcpeck,<br /><br />I almost passed on this but Lubedude and I have MAJOR differences of opinion here. He's a salesman and I'm a user. Your 200s will run forever on regular TCW-III rated oils thank you. If you decarbon every 250 hrs the risk of damage caused by carbon build up is about zero. Decarbing also takes out unburnt fuel deposits.<br /> <br />Ask any synthetic oil rep for independent testing to prove claims as being cost effective in wear hours. They can't or won't do it. Also, Amsoil isn't TCW-III certified and only claims to exceed that rating in their advertising. The advertising only leads you to believe they are certified. A certain unnamed rep says the TCW-III is below "their" standards but does NOT give proof in any way other than advertising. Playing down the TCW-III rating is done by products that can't hack it. It's easier and cheaper not to get the certification. <br /><br />Also, oils that don't have the official TCW-III certification do NOT meet the specs in your motor manual. Running an oil without the certification will bust your warranty. No ifs, ands or buts about it. Ask your motor mfg if you need proof. They can legally spec certifications but not oil brands. Check it out with your lawyer.<br /><br />In case you don't know, anyone who sends a small (VERY small)check to Amsoil can be a dealer...no formal experience, certifications or education on oil or motors required. <br />

Re: synthetic oil

BillP, first of all, carbon build-up IS damaging, and CAN be prevented with the proper use of the correct synthetics.<br />I'm a user as well, and have done MY OWN testing of SEVERAL different brands of oil, and please, you have to understand the reason Amsoil is not TC rated, that reason being it is so far superior to conventional oils, It's not even considered.<br />Johnson/Evinrude XD-series oils have no TC rating....Explain that, please.<br />Ficht Ram has no TC rating...Explanation??<br />Running NON-TC-W3 synthetics WILL NOT void your warranty, and is bogus information, period.<br /><br />

In case you don't know, anyone who sends a small (VERY small)check to Amsoil can be a dealer...no formal experience, certifications or education on oil or motors required. <br />

As oposed to costing nothing to provide biased, unknowledgable information.<br />The Dealer may make the original sale, but it sells itself from there.....Do you suppose Walmart has a Lubrication specialist on hand to help with customer sales??????

Re: synthetic oil

Are there any articles available in professional petrochemical or marine engine publications on this subject? Given the fact that on this board some vested interests seem to be involved , it would be very helpful for the average CONSUMER to have impartial information available . Does anyone have any references of this kind? If so, please pass it on.

Re: synthetic oil

There only have been 2 true oil testing articles that I've read in the boating magazines over the years. Most were just one author's opinion from talking to different companies.<br /><br />Bass and Walleye boats just came out with a 4-stroke oil comparison, oil analysis on a Yamaha F225, and a rust test in the March issue. Back in August of 2000, they did a 2-stroke oil lab test to see if any of the oils were similar. Each oil was different except for Exxon and WalMart.

Re: synthetic oil

As a Merc. engineer said "Oil Is oil; It's what you add to It that makes the difference. A tcw III rating Is an absolute minimum rating. Engine manufactures have their oils blended for them. They take a base oil and add an additive package. The general public thinks the engine manufactures are trying to get them to buy their oil to rip them off or make 'GOBS" of money from selling oil. Not true. As for mixing 100:1, This practice Is no longer recommended by most manufactures 'cause there Is not enough residual oil left In suspension to keep Internal part from rusting when the engine has not been run for long periods of time; I.E more than a week or 10 days.....

Re: synthetic oil

One more question about synthetics. Is there enough residual film left over from synthetics at 50:1 to protect internal part for a week to 10 days. Most of the time my boat sits for at least 5 days between uses, usually no more than that, but sometimes 7 or 8. I really would like to have that residue in there for the week, I know reg. oil will provide that for me, along with alot of smoke and carbon build up, and maybe not as good protection, but if synthetics will provide a decent residue for a week, then I am sold. And also if the Amsoil saber outboard oil is ok to run at 100:1, what will it do when I use it with my VRO, since this is a50:1 system, I assume it will be fine and still burn way cleaner than reg. oil at 50:1 through the VRO. Thanks.

Re: synthetic oil

The Amsoil Saber is for Pre-Mix only.<br />DO NOT use it in an injection system.<br />For your VRO use the HPI oil. It will protect over the long term as good as any petro oil and perform better when being used.
