Petrol in a bike how long is it good for?

We've local filling stations/supermarkets with very high turnover which may help with fuel dating and their tank storage for condition etc, don't use anything special in the way of grades to avoid E either.

We've a 1991 V8 petrol with injection system that I'm running with 1% castor oil continuously since E10 has been around, no problem experienced with that and perception of no water attraction with this (I've static samples sitting in jars to assess mix effects and dropout)  also don't mind carrying a can to run tank out to clear or run risky range with contingency.  This one is plastic tank but system is clean as a whistle (I can get into top of tank for inspection to see if there's anything in there) but generally all good.  Cap is sealed on this one with carbon filter and air/emmisions containment fitted.

Perception, I'll emphasize that, is that E fuel is more stable with oil added in low ratio, castor smells nice too.

The 1% castor oil sounds like one of those Edd China top-tips Nigel, I'm going to try that in my bikes. Where do you buy the castor from these days, I used to buy mine on a Thursday night at Wimbledon Speedway but haven't seen it around for years even at Kempton Park.

It's on e bay under cosmetics.

Dave, the supply I've used is this https://www.amazon.co.uk/Castor-Oil-litres-Pure-Pressed/dp/B06WVD519M/ref=asc_df_B06WVD519M/?tag=googshopuk-21&linkCode=df0&hvadid=344355771029&hvpos=&hvnetw=g&hvrand=11054008386220214821&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=9045909&hvtargid=pla-685207637751&psc=1as just a pure castor oil.

Not being used for primary lubricant (for that you'd need a proprietary motor specification) but as mitigation in E fuels. I most definitely don't believe in "miracle" products in this field and don't believe this can do that. To make it clear, soft material incompatibility like rubber and seals etc being vulnerable is not something that can be accommodated with an additive in my view, making that aspect something to consider separately.  But with separation from storage and ability to reduce potential metal corrosion within fuel systems, then this tentatively appears to offer performance advantage.
Castor has extensively been used in alcohol fuel with methanol and has no problem mixing with this and petrol. My static samples held for some period of time seem really stable.

And so, some potential to consider but I'd encourage others to make their own evaluation to assess this seperate to my observations.  Adding 10ml per litre of petrol will give a start ratio of 100/1 making it easy to try it. Even at 15ml giving 75/1 it can't be seen smoking, but with enhanced smell.

Definitely something to consider for those interested.

McCabe-Thiele (Ted):
Could Castrol R be used as an alternative ?

I used to put it in my Petrol back in the 1960's just for the aroma!

Yes Ted, it's the same base oil in that product.

Castrol is effectively named after "castor oil" by contraction of the two words. History of "Castrol" is the company started as CC Wakefield  making oil products for machinery, research led them to using castor oil as base to build motor oils because of it's most substantial characteristic (it's structure is really hard to break down under pressure, making it a very resilient lubricant with high shear properties) being ideal to keep moving components from wearing each other during use. Ultimately so successful that CC Wakefield was rebranded as Castrol.

The R in the name of "Castrol R" is not as many suspect meant to denote Racing, but of it's origin in "Ricinus" oil (also the potential origin of Ricin poison) which brings that R to the party. Poisons in other beans are arsenic in broad beans and kidney beans too, the subversive little boogers  ;D

The castrol R product will contain other elements to make it specific to engine lubrication, components to control ph, zddp etc likely. Cost is much more than cosmetic plain castor and those components are not needed for this topic I believe. It's more that at 1% addition it's effectively 10% ish of ethanol content in E 10 fuel and so may have a significant binding effect with the E component to reduce it's attraction of water. Speculative yes, but seems to offer potential.
