Title: Additives
Post by: RIngrey on October 26, 2011, 03:43:54 PM: In anticipation of the colder weather I thought it wise to invest in some additives to prevent issues developing over the winter period.
I know some of you will choose to add a little petrol and mix with regular derv but I decided to give the commercially available additives a try.
I purchased some Coldflow 350 and BioBoost 1000. Having made a few batches now I have to say the difference is quite astounding. My Bio's viscosity has totally changed and together with the Bioboost performance has increased also. I can't vouch for any increases in MPG as of yet as I have not done any calculations to date. However, cold starting has improved considerably and throttle response has also benefitted.
I thought I would share my experiences with you all now that the colder weather is set to draw in.
All up the cost is minimal and well worth the outlay.

Also doesn't 1u filtering take the additives out again? (I always 1u cold filter before it goes in the car)

Not so much hot as warm,either 20C or 5 above the cloud point and the companys now say they can be filtered to (and incl) 1 micron

the only think i dont do in the winter is use solids i use 100% liquid but right now its 80 liquid 20 solids until i get a cload and its time to stop the solids

...to put them in the wiki?

The table definitely helps with the readability of the results.

It will surely sit better in the "Safety and testing" category as it's not part of the production process and the clue appears to be in the page title ... testing!!!

Can we add a little more info on the viscosity test and the drip cup? I can hazard a guess as to how it works but some photos and a little text would compliment the already excellent information.
