Re-cap Rhino v premium
I've been very impressed using Rhino at the continuous 1ml per litre dose for a year now but just for fun occasionally I've popped in 3ml per litre --- a lot of fun , especially on track. However , you can get used to things , so thought I'd try Shell's V Nitro as opposed to simply premium deisel.
This presents me with a problem ie. I can say that V Nitro is definitely a better performance fuel based on response and power through the range than my previous standard SHELL/BP or ESSO plus 1ml per litre of Rhino . BUT It's a fine point in comparison to running standard fuel plus 3ml Rhino. ----------- I can't actually say which is best.
Not running each on the same day , one immediately after the other , means it's very subjective but I think they're about equal. Of course cash wise is a different story --- rhino wins.
