What exactly IS the deal with Amsoil? Ive heard some horrible things about Amsoil and outboards, whats the deal with it as a car lube? is it better than the other synthetics, such as Mobil 1?<br /><br />boomyal related how he uses amsoil and long filter changes, and the salesman told me a buddy of HIS does the exact same thing!!!! 9 hours I hear about synthetic oil, I dont know if the salesman said amsoil or not<br /><br />thats the real deal here?<br /><br /> :confused:

Re: Amsoil vs Mobil ! and the rest of the synthetics

Ray, I take it you read the other post that got zapped.. I usually agree with the majority here as they are a knowledgeable bunch,, their knowledge of boats and motors is nothing short of awesome.<br /><br />On this one I have to disagree, I run Amsoil MC air-cooled oil in my HD and it is the best oil I have ever run in it. It runs cooler, quieter,and even my mileage went up a hair.<br /><br />This summer when I was out west a bud of mine road down from salt lake and joined me in Vegas. We road across the dessert to California and it was 110 degrees.<br /><br />I was running amsoil and he conventional oil( Note we have the same year bikes with the same motors) His motor was running hotter than mine and was really tapping away,, HD's will do that. My bike was as quite as it has ever been. <br /><br />This tells me the amsoil was doing a better job. Also I now run twice as far without a change.<br /><br />This has been my experiance with the stuff. The bike shops cant keep it on the shelfs around here.<br /><br />And NO!! I dont sell the stuff.<br /><br />Ok Pat you can stomp me now :D

Re: Amsoil vs Mobil ! and the rest of the synthetics

I myself have never tried these types of oil.<br />Mainly I guess because I was afraid that after using regular oil, it would hurt my engines in someway.<br /><br />Do you have to do any thing special to switch to these oils?<br /><br />Flush the engine out with some special cleaner or anything?<br />I was just always confused :confused: about all this.<br /><br />But with that said, I have heard good reports on it.

Spinner when I put it in the first time I just let it drain real good, no flushing or anything like that. I would say the one thing you might watch is using a cheap oil filter.

Thanks head.<br />Do these oils work good in diesels also?<br /><br />I would not change it my courier vehicles, that would run into some $$$'s but might in my own vehicles.

I could not say about diesels or cars, I still run regular oils in my 4 wheeled vehicles. But am thinking of making the switch.

Re: Amsoil vs Mobil ! and the rest of the synthetics

Amsoil is good stuff. So is Castrol Synthetic. I prefer Mobil 1 because of it's availability and the fact that Mercedes Benz recommends it for my ML.<br /><br />Oil change periods on my ML are determined by computer monitoring of vehicle use, oil temp, oil pressure and other parameters. The 'puter has told me to change my Mobil 1 at as little as 6,000 miles and as long as 13,000.<br /><br />At 120,000 miles there is no sign of wear, no oil usage between changes. :)

Re: Amsoil vs Mobil ! and the rest of the synthetics

I do know for a fact that Mobil 1, Castrol Syntec and Valvoline Synthetic oils are all approved for aviation use!<br /><br />I know for a fact that AMZOIL is not!<br /><br />Mobil 1 is also approved for use in the space shuttle and AMZOIL is not!<br /><br />I'll stick to what those, whose lives depend on the oil in their crankcase, use in their engines.

Re: Amsoil vs Mobil ! and the rest of the synthetics

Spinner_bait Nut, yes it works well but Diesels are a different animal, for years amsoil only offered a para-synthetic(to keep the price down) because diesels, by their nature foul lubricating oil prodigiously. So you couldn't do the extended oil change routine to mitigate the higher cost of synthetic. They now offer 15w-40 full synthetic (same as marine), for higher bearing protection, but I haven't checked their oil change recommedations. There is no doubt that I far exceed Amsoils oil change recommedations but unless I incurr an event that would contaminate the oil I stick with my experience.<br /><br />As to converting to synthetic:<br /> Don't convert a high mileage engine as it may be sealed up with gums, varnishes, sludge, etc that may be keeping the engine from leaking. Synthetic will clean all that stuff out. Back in the days of cardbaord oil cans, Amsoil had to pack the oil in full metal cans to contain it.<br /> Don't convert a new enginge till it is broken in and not using any oil. An engine will not break in using synthetic<br /> For low to medium mileage engines in good shape, add a can of synthetic to your petroleum oil and run it for a thousand miles to clean out any stuff that has accumulated in your engine, then drain it all, hot, and fill'er up with synthetic.<br /> If you don't go with bypass filtration, at least use the highest quality oem filter (yes there is a difference) follow Amsoils recommended oil change intervals and DON"T try to use the oil change program I use.<br /><br />Bypass filtration removes particles something like 4 times smaller than than ANY oem cartdridge replacement.

Re: Amsoil vs Mobil ! and the rest of the synthetics

My one bud that does machine work said he can tell if a part had synthetic oil vs one without.<br /><br />He said the cutting bits do their job as they are supose to except when it comes to the synthetic oiled pieces. The cutting bits don't cut as well and makes it more tricky in getting the machineing to its tolerances.<br /><br />I use lots of the synthetic, but haven't been convinced on Amszoil. IMHO......SS

Re: Amsoil vs Mobil ! and the rest of the synthetics

My Honda outboard is using Redline synthetic. As soon as I'm done with the case I'll go to Mobil1. Only because it's probably every bit as good and is easier and cheaper to come by.<br /><br />My wifes Mercedes, the F250, Harley, Toyota, Wrangler, and the Honda lawnmower all are using Mobil 1. <br />No leaks, no drips, no errors.

Re: Amsoil vs Mobil ! and the rest of the synthetics

I run Mobil 1 in my cars and love it. As far a Amsoil is concerened, untill they get an API certification and a TC-W3 approved they will never be in anything I own. I am not saying the stuff is not good, but I challange anyone to find any "independent" testing of Amsoil, and I am not talking about that joke of a webpage from them. If something ever happend to any engine because of oil related failure still under warranty you would be outa luck with out these certifications. The manufacures would not have to prove that the Amsoil did it (like they tell you at there site) because they clearly state that you must use a certified oil. Again, not saying it is not a good product, I just want certification and independent testing, not propaganda.

Texskeeter...you got that right! I've been asking for independent labs tests on Amsoil from the "cult" but nobody has acknowledged my requests. I get bashed instead.

Re: Amsoil vs Mobil ! and the rest of the synthetics

BillP, <br />The worst part is how the insinuate that they are certified with words like "meets" and "surpasses" but you will not find the stamps on any of their products. I just don't trust the way they do business. They don't back up one single thing they say or claim with "indepenent" testing or certifications.

Re: Amsoil vs Mobil ! and the rest of the synthetics

I admit I dont know too much about these oils, but I do know that Flathead LOVES his hawgs, 110 degrees? Ummmm, yeah, no DOUBT he loves em, and he uses the stuff - and the bike ran great in blistering heat<br /><br />thats a mighty big engine to be trusting air to cool, especially when riding in an oven!

Re: Amsoil vs Mobil ! and the rest of the synthetics

Boy! This is starting to sound like an "Amsoil, the Synthetic Oil you love to hate" post. <br />Well even tho I have no axe to grind specifically for Amsoil, I do have one to grind for Synthetics in general. They are undeniably far superior, in every measurement, to Dino oil. <br /><br />I mention Amsoil, because I have been using it since b4 there was a Mobil 1 or any other synthetic oil for civilian use. They were a pioneer in the field.<br /><br />It is simply the one that I can give personal testimony to.

Re: Amsoil vs Mobil ! and the rest of the synthetics

HI! i have torturtested mobil 1 in my turbocharged 1600cc escort ( 1.5bar boost) 260hp..manifolds yellow from heat....drove it several years ..lot of extrem driving.. pistons and bearings like new! (no charcoild oil and very clean inside) almost every car here in europa is recomended to use synt oil....and service book say that if you use mineral oil you must change oil more often to maintain warranty.. engines will breakein but it will take a longer time because it lubes better...but i got the time cos i will uuse it many years!! :D
