The problem is not the can. It's the gas tank. It eats o rings............

Ya I know not to leave it in the bike, but does it have a can life before there is no performance advantage from it. I have 3 gallons and have had it for about a month now.

I never drain the tank on the 12...I have been using MR9 since the 2004 season with the fuel in the tank from March to November!!!...In November of 2005 the fuel pump crapped out...Not bad for only removing the MR9 over the winter...

If you seal it properly, it will last indefinately!
What is the best way to store VP Racing Gasoline?
As long as the gasoline is kept in a tightly sealed container, the storage is indefinite. These gasolines contain olefinic hydroccarbons in negligible concentrations, thus their tendency to form gums and varnishes is negligible. The gasoline will not separate as its components are solvents of each other.

Here is a word of caution about MR9 from Brock's website:
http://www.brockracing.com/forum/display_topic_threads.asp?ForumID=16&TopicID=455&PagePosition=1
Well, after convincing ourselves that VP MR9 fuel wasn't as hard on Fuel systems as Nutec.....SURPRISE!
We have THREE bikes with DEAD fuel pumps after leaving this stuff in the tank for over a month!!
Retail price on an "in the tank pump" (Hayabusa, GSX-R 1000 etc.) is right at $500.00
It is a $1500.00 mistake we don't want you to make!!!
According to our sources (American Suzuki included.) MR9 will not damage the pumps if left in the tank for a day or so....or even as long as 1 week. But anything close to 1 month...it's over.
They recommend draining the tank and running pump gas through the system after every use. This is what the road race teams do before they head back home. They are also careful to COMPLETELY SUBMERGE the pump in gas...not just add a little for the flush.
I have posted previously that we had not seen problems leaving MR9 in the tank between weekly trips to the drag strip...BUT, one Hayabusa test did keep loosing mph as the season progressed?
HMMMM.....if MR9 completely destroys a fuel pump in a month, I wonder if it will slowly hurt performance before it dies completely?!
In the same breath, BOTH of our GSXR1000's ran their best MPH's at the last race and they did not have pump gas in the tanks during the entire season?! Each bike was raced at least once per week.
This is a new mystery to solve....
We will figure it out and pass the news on to YOU!
I'll keep you posted,
Brock

This is no mystery....VP gas cans have the warning on them for a reason. I believe it reads "Do not store in fuel tank".  The warning is there for a reason....it ruins very expensive shit

There is a 3 to 4 weeks between our CMRA events. All tanks are drained and fuel systems are flushed before we leave the track. Luckily, it's pretty easy on the two stroke bikes (TZ 250/125 & RS 125), but more of a hassle on the 600s. We do this only because by the time we get back home (usually between 10 pm to 2 am), we tend to forget about the bikes for about a week or so after the event. Leaving MR9 in the tank/fuel system for three weeks or so can get real ugly. Don't ask how I would know. I ain't tellin'.
When we store any of our VP fuels (C12, U4, U2 or MR9) in between races, we will use only two types of containers. If it is less than 5 gallons, we will use a metal can, but not necessarily the one it came in. I could be wrong, but I think the blue cans usually have the plastic spouts and caps while the black cans have the metal ones. We will only use the black ones to store fuel.
The cans with the plastic spout pour better, but once opened, the plastic cap does not seal tight and the plastic spout itself, will let air pass through ("breathe"). When reusing the metal caps, make sure the "paper" seal inside the caps are in good condition. We also will not use a metal can for storage that has had the dreaded metal funnel removed, because it can distort the metal opening of the can. As a extra precaution, we will completely cover the cap and the area around it with a couple pieces of duct tape.
If it is more then 10 gallons (never the case with MR9) we will use a VP 15 gallon drum. We try to fill where there's the least amount of air inside before tightening the bungs (screw caps). Again, always checking the condition of the o-rings.
We NEVER use a plastic jug to store any fuel for an extended period. Plastic "breathes". We won't put MR9 in a plastic jug for even short amounts of time, unless it will be used within a hour or less and that's only because the Quik-Fill we use in endurance racing doesn't fit the metal can. We can go through as much as 25 gallons of VP fuel in a single endurance race (up to 8 hours long).
When ever we transfer fuel from one container to another (or to/from a tank), we always use a funnel with a fine screen in it. Even a new can of VP fuel could have some debris in it. It's very rare, but it is not impossible either. You can automatically assume that there will be some amount of debris in them from repeatedly transferring the fuel from 5 gallon cans to fuel tanks and back into the cans or drums. Since we use the "storage" cans and drums for the whole season, we'll regularly inspect and flush them to reduce the possibility of debris and make sure they seal properly.
We also try to keep the fuel as cool as possible. At the track, we'll keep it in the A/C cooled trailer and only bring them out when they will be used. If is sealed properly, they won't stink up the trailer. When the cans are not in the trailer, we try to keep them in the shade. Between events, they are stored in a garage with A/C. If that is not possible, just find the coolest spot in the garage that is not in direct sunlight.
It might sound like a hassle, but were "cheap" and when your buying as much as 400 gallons of VP fuels (mostly U4 and U2) a season, you try to keep every drop as "fresh" as possible in between races. For something as pricey as MR9, we're "real cheap" and cautious. Leftover C12 is just dumped into our street bikes or pit scooter (or generator).

Red, just to let you know that there was a race team storing VP race fuel in a metal fully sealed gas can that was DOT approved for transportation in vehicles so that they would not get introuble for transporting the gas...
Anyway, a test was done to check proper fuel and they were DQ'd because there was something else in the fuel...They fought it and found that the DOT gas can was contaminating the VP fuel due to whatever was on the inside of the DOT can!!!
Always store the VP fuel in the issued cans!!!

CR, our black 5 gallon cans (usually U2 and U4) and drums (blue) are VP issued and labeled. You can request them instead of the blue cans from your bulk dealer or area distributor. The only down side to them is that the metal sleeve funnel in the can doesn't work worth a crap.
I flush them with a type of lacquer thinner that is custom blended in 55 gallon drums for my work. Because the process we use it for at work, we have to spec it to have a extremely high evaporation rate and leaves no trace residue. Just don't get it on the can's paint, it will eat it off in a heartbeat. Makes most acetones look like water. Oh yeah... and it is EXTREMELY flammable.
Makes a great parts cleaner too. As long as theres no plastic or rubber in it. Melts it immediately.
