Is putting Mobil 1 in 1980 GS1100E with 89,500 miles ok?

[Anonymous]

I just got this bike and I want to make sure it lasts. I'd like to put Mobil 1 in it....is there any danger in doing so with a bike so old?

Please help! Thanks!

With that many miles I wonder if it will LEAK.......I also would find out what they were using in the bike before......Do you really need the synthetic??

I found these two things on another site. Very interesting reading. Very clear and easy to understand.

Have fun learning.

Just do it--you wont hurt the motor--if it leaks then switch back--i started using synthetic oil in my 1100e at over 40k miles and i can only attribute any leakage that i have had to leaving my petcock on and diluting the oil or a worn O ring in the auto cam adjuster. After a couple of oil changes(just after the petcock thing) the seeping stopped again(still using synthetic oil)- it wont dammage your engine and if you experience clutch slippage the chances are that you clutch need attention. As long as there is oil in your engine i dont think tha you can do dammage. If there are any exceptions to this, i'm sure someone will tell us about them

Roman, that was a very interesting link on the oil. I have been using the Delvac 1300 in my Gold Wing for about 2500 miles now, will have a good look at it when I change oil in a couple of weeks. At $5.88 a gallon at WalMart, it is an inexpensive alternative to synthetic. The only hesitations I have about using the synthetics is that I don't feel they are worth the extra cost unless you are going to extend you oil change interval. The one time I tried using a synthetic in my GS1100E, I had leekage around almost every seam on the engine. Since I would rather ride than clean my bike, I switched back at the next oil change.

Kinda how I feel about them 8O

im with you on all that al i just use it for the extra slippage on the bearings :lol: . I was fortunate not to get leaks--probably because i only put it in right after i installed the 1166 kit

When you switched over to synthetics, did you notice an increase in fuel economy?

All I noticed was that the oil temperature was better--lower--wwhen i put the 1166 kit in my oil twmperature went up a bit and when i installed the synthetic oil it went back to normal something like that

Just got it with 89,500 miles on it? Holy miracle mile, Batman! I have done a lot of research on oil- it's an interesting topic of gearhead conversation. Syn oil should not do any damage to anything. Your bike should not leak anywhere with any kind of fluid. If it does, it is a sign of somthing that needs attention. I have heard stories of clutch slippage happening more with syn oil, but it doesn't really make sense, mechanically speaking. I myself have used both syn and dyno oil from time to time with no change in perfromance what so ever. A lot of people believe that you can go longer between oil changes with synthetic oil- that's not really true either. It's not the viscosity breakdown that nessecitates an oil change (or shouldn't, for those of us who value our rides) but rather the fact that a certain degree of normal wear on engine parts can spoil the lube with forgin matter, not to mention the additives that are placed in commercial gasoline, and... I'm gonna stop now. Do some reading in previous posts, there is a lot of oil related conversation of value there. Simply put, syn oil doesn't hurt anything, but it won't help the bike last longer. That's what a good manual and tool box are for.

What is the purpose of using synthetic oil???

Oh I can't resist, I just can't resist.....Scotty you forgot to mention the 20 or 30 times you've dropped it in the driveway...he he he...

Synthetic oil was designed by General Electric in the 1940's to lubricate turbine engines. These engines have a normal operating temp in excess of 800 degrees. Depending on the configuration of the oil, dyno oil breaks down somewhere between 300-500 degrees. If I felt synthetic oil was any better for my bike I would gladly buy it at any cost. The fact of the matter is that it doesn't make much of a difference either way, as long as you change it when it is dirty.

the actual fact is that we all use what we want

I noticed that in a driveway drop 8O synthetic oil landed 50 percent softer than dyno oil. The problem was that it didnt make my butt hurt any less :lol: This is an un desputable fact

That's the truth. If it works, keep doin' it!

Synthetic Oil

Synthetic Oil

About 2 years ago I read an article in a Consumer Reports-type of magazine (can't remember which) about synthetic vs. regular oil. The test used a fleet of New York City cabs as guinea pigs. Both types of oils were used in cabs whose oil was changed at 3000, 6000, and 10000 mi intervals. I believe that the engines were torn down at 100K miles (or something like that), and surprisingly the only difference in the condition of the engines was attributed to the frequency of oil changes and not the type of oil used. The 3k and 6K engines were nearly identical in condition, but the 10k engines showed significantly more wear. Bottom line: change the oil frequently, and as long as you use the right viscocity of decent quality of oil you shouldn't have a problem.

Oh, but the truth is though, that dyno oils are well broken down long before the specified change duration -- like within the first 1000 miles or so (depending on the service), but you can't sell that, nor do you need to 8O It's rare to have an engine -- in your possesion -- long enough for you to reap the reward of your labors. You'll trade it in and the next bloke will be dealing with it. So, 3000 miles is recommended even though it's probably long past time to change it.

Dirt is one thing -- you've got to change oil and filters regularly, but lubrication properties are another. Synthetics typically do not break down like dyno oils. It's this breakdown that causes sludge to form, which is the worst kind of dirt your engine deals with -- apart from dust particles inhales by the carb. They also don't attach (bond to) a lot of the other chemicals (from the air and gas and combustion) that cause premature oil degradation. So, synthetics will prolong the life of the engine -- when used from the get-go.

Engine oil serves two main purposes: to keep metal parts seperated by a film tougher than the force applied to them (viscosity) and to provide a resultant cooling (friction reduction). The fact that synthetics do not so easily break down and that they provide superior viscosity retention, they do not allow for the increased temperature increases that can play such a big role in the oils failure. In essence synthetic oils prolong their own life -- in a way.

The problem with synthetics is: Once an engine has been "gummed up" so to speak, by petroleum based oils, the only thing synthetics will do is clean it up inside -- so much so -- that the seals that used to be gummed up (and are subsequently hardened) with the what-nots left from dyno oils will begin to leak eventually. I don't think this is of much debate. I used to deal in AmsOil and they were well on the cutting edge of this research then for automotive use. They had proven research that synthetic oil can clean an engine, but also (as a result) recommended users NOT to use the product on older engines for that very reason. They sold a para-synthetic oil for older vehicles.

I'm not a 100% user of synthetics either, but will use it if I built the motor and want it to last. One thing I can say... when, and if, I ever take a motor apart that has run on synthetics -- the engine is pristene inside.

That's my 2 dollars and fifty cents worth... :wink:

I used full synthetic once many years ago. Being young and not knowing any better, I was changing the oil in my Dodge and reasoned that if adding a quart of slick 50 to my car was good, then putting only slick 50 into my bike (Honda) would be wonderful and nothing would ever wear at all or at least not for the first million miles. Well, it didnt fall over in the driveway, because it wouldnt move. Redline the tach and pop the clutch in 1st and the bike wouldnt roll 1/4" at full throttle with the clutch fully engaged.

That should say a lot for what Slick 50 could do to combat wear and tear on a engine (as long as it doesn't have a wet clutch). I've personally never used it.

Were you able to just change out the teflon impregnated oil, or did you have change the clutch discs too?
