I've been thinking that using high grade Mobil 1 V-Twin synthetic it would probably be a good idea to change the filter midstream and keep the oil in place. If I take the oil filter off to put new one on am I going to get an oil gusher?

Have SuperTech Filter on now.

Chk this out,i pasted below this statement directly from mobile1 website for their v-twin syn oil and it looks as though from ther reswponce to question of mileage the v-twin syn should be changes that 5k miles is about it,not 8k miles like /amsoil claims their bike oil can go.

HHHMMM,makes me wondewr,i saw an extensive oil test recently done on many bike oils by mult oil mfg's and the mobile 1 v-twin 20-50 syn and amsoil syn mcv 20-50 oils perf very close to eachother but amsoil did better the mobile by a hair but those oils outperformed the others oil NP at all.

But since the mobil 1 oil perf almost as good as the amsoil why the diff of 5k vs 8k oil change rec?

Is the amsoil really that much better (which didnt show that was the case in oil testing i read) to go a full 8k miles inbetween oil & filter changes or are the Mobile oil engineers being more conservative on thier oil change rec of 5k miles because all motors arent running under best case senario all time and they want to be sure your motor is always protected well? You know like running the bike in much more dirty/dusty cond in hi temps maybe running rich which can contam the oil fatser too vs running a bike in cleaner air cond at more moderate temps with fuel calibration correct and not too rich etc.

But i case of only going 5k miles with the mobile 1 v-twin 20-50 syn oil i feel theres no need at all to change the oil filter mid stream when running mobil's rec of 5k mile oil change schd.

I run that Mobile oil which is approx $1.50-$2 per qt cheaper then the masoil where i live so i will stick to thier 5k rec oil & filter change schd and ot change the oil filter midstreem in only 5k miles.

I still feel that mobile 1 oils ability to better protect the motor then conven oil can ever do on top of getting an additonal 1,000 more miles out of each oil change is worth the additonal $20 per oil change i spend for a lot better protection and the additonal 1,000 miles inbetween oil changes.

Anway heres mobil's responce directly from their website to a question on the oil change schd for their full syn v-twin 20-50 oil.

The owner's manual says I should change the oil every 5,000 miles or once a year. I change my oil every 2,500 miles or twice a year. So why do I need that kind of protection?

For peace of mind and added protection. You pay a lot for a bike these days, so why risk running your engine in ordinary oil? Just like Mobil 1 synthetic oil for cars, Mobil 1 synthetic motorcycle oil helps keep your engine clean – free from varnish and deposits – and smooth running mile after mile, no matter what conditions you ride in.

Mobil 1 benefits engine life and performance. In fact, the lubrication capability of Mobil 1 motorcycle oil helps maintain peak horsepower and acceleration throughout the life of your engine. And with Mobil 1 you can go the full 5,000 miles between oil changes.

So, if you want to ride your bike long and hard and not be concerned about the oil, choose Mobil 1 motorcycle oil.

I run the mobil 1 filter and for $10.00 i will change it around 2500 miles to remove any contaminants it might have picked up,especially now that its the first time i am running mobil 1 v-twin 20w50 synthetic switching over from standard oil...the synthetic is supposed to really clean the motor so if any crap is in there it should be removed with the first filter change..after 5-6k on the oil i will do a complete oil change at $10.00 a quart..its not supposed to break down like conventional oil especially under hot conditions..which is why i put it in my bike to begin with..

Here is the reasoning, and I am surprised at how many have not heard of it. It is a common practice when running synthetic.

Synthetic oil can be run twice as long, and sometimes more, than dino. Typically 6000 mile oil change intervals on average, depending on the oil used. The idea of changing the filter mid way between oil changes is really a precautionary measure to insure the filter does not become restricted with contaminants and go into bypass. If your engine is running correctly, has no problems with SVS, carbon build up, etc. there should really be no significant contaminants present that would cause a blocked filter. With that said, I do recommend changing the filter at mid interval.

I run Amsoil 20W-50 Motorcycle Oil and a Mobil 1 M1-110 filter. I choose to run 50W because of the extreme hot Texas summers here. I currently have about 7400 miles on my oil and filter with no problems. I did not change the filter at the mid way point however, as previously mentioned, I do recommend changing the filter at mid interval. For the cost of the filter, it is cheap insurance and peace of mind. I intended to change the oil and filter at 6000 miles. I will be changing both soon.

The answer to the question is, you will lose the oil in your filter and a bit more from the engine, but not much. Remove the old filter, and immediately install the new one to minimize what you lose from the engine. As mentioned, some will come from the filter housing when the filter is removed however, the oil will not come gushing out. It will be restricted to whatever oil is immediately adjacent to, and in the filter housing.

BTW, I had a run up to Millington TN last weekend. We ran 80-85 MPH all the way up and all the way back, and I started the trip on my 6000+ mile Amsoil and Mobil 1 filter. She never missed a beat and never had a problem with heat. The bike ran flawlessly and effortlessly. I have 1100 and some change on the trip meter for the run.

Just wondering why your being kinda defensive when nobody or myself said you could not run your amsoil 6k miles or more inbetween oil changes,amsoil rec 8k with thier oil in our bikes which i already stated in my post.

I simply stated amsoil rec 8k miles oil changes and mobile 1 rec 5k mile oil changes and both those oils seemd to perf very close in oil testing i'd read up on with amsoil slightly edgeing out the mobile 1 but wondered why such a dif oilchange rec from the mfg's.

I was not trying to start a debate on that,what i was doing is the original poster stated he wanted to do mid term oil filter changes and that he may not be aware that mobil rec 5k oil change schd with thier v-twin 20-50 oil. So i that case why bother with mid term oil filter change at 2500 miles which would be a waste of time & money for him to do if he follows the oil mfg's rec of 5k mile oil change schd ,amsoil is a diff mfg with a significantly dif oil change rec .

This was not comming from me ort my opinion,this was comming right from the oil mfg for 5k mile oil change schd with the mobil oil so thats about all i can say on that one other then i would expect that mobil 1 v-twin oil to last a little longer/go futher then conven oil which per mobil's std /rec does but only be an additional 1,000 miles . But i bet even 6k mile would be fine on the mobil oil esp if not used in harsh dirty hot cond.

I'm just about ready for an oil change, I have close to 8k on the amsoil and the pure one filter,,I'm impressed with them both, the oil still looks almost as clean as the day I put it in, so the filter must be working pretty good.......

I regret you interpreted something in my post that you perceived to be defensive. On the contrary, I was just giving the numbers that I have experienced for the general knowledge of the forum members. I have no problem here. Actually the intent of my post was to point out the awesome R* machine and a tribute the the Mobil 1 filter. Point out the problem you have with my post, and I will edit it out for you.

That is impressive. Looks like I am not the only one that ran the filter double duty. It is good to know that these filters will go that long. I am impressed with the Pure One and Mobil 1 filters.

For clarification, I think my last post was confusing for some. I had previously elected to change my Amsoil at 6000 mile intervals instead of 8000. My post reflected that and I think it confused some that I was taking a defensive stance. Sorry about the confusion folks. Not defensive here, just posting numbers.

What's the deal change the oil change the filter. The point in changing the oil is to replenish the engine with clean oil as is the filter. If you want to change it more often don't use synthetic oil and use regular oil. It can be bought at discount prices as are the filters.

Para,

I want to use Synthetic. Not sure what your intent is but your comment isn't helpful. I'll do what I want with my bike thank you.

roadhawg and scottw.. thank you both for the info..
