is it ok to top up with super unleaded if you already have unleaded in the tank?
yeah, won’t do any harm (except to your wallet) 
Cheers Mark.
Thanks Sutcir. Did I forget to mention all donations to my petrol fund are welcome 
if you’re near an Asda dude, their ‘super’ is at 93.9p per litre. I filled up yesterday with normal unleaded and it was only 91.9p, much cheaper than the BP garage up the road at 97.9p.
Filled up with super unleaded the other day, as I finished saw that the price was over £1;03 !!!
BP Kennington Lane !!
Petrol does seem to be edging back down in price. Don’t do what one of my uncles friends did and and thats go to a track day and fill up on racing unleaded. He reaconed it was £35.00 a litre not sure how true that is.
£35.00??? Asda here I come The chappie who tuned the engine said to use super as my compression ratio is a little higher than standard.
