which one you considering ? they do a few in the range - millers site is full of cracking info and not just on boosters but oils as well

CVL Turbo is suitable for occasional use in vehicles fitted with catalytic converters and is compatible with nitrous injection systems. Use Millers Octane Plus for continuous use in catalyst equipped vehicles.

the Rad hib is good stuff too - but then im biased - i sell it :p
 
Yeah was thinking of the millers octane plus.

Mainly want to use it because the nearest shell garage to me for optimax is quite a drive and tesco dont do 99ron in the midlands.

SO was going to consider using octane plus with bp ultimate?
 
in laymans terms i guess its like giving a smackhead a regular supply of cannabis - will keep em sweet all day but the weekends let em have a full load ;)

if ya using it for regular fillups/driving use octane plus
 
I use millers octane plus with every tank of optimax and have had no problems,so go for it;)

Same here but now trying out Tesco's 99 without Millers.
I'll try and log timing after a couple of tank fulls to see if there's any extra timing pull.

I found a place local to me which was willing to sell Millers Octane + quite cheap if bought in bulk, last buy was for 40 bottles which worked out at £2.60 per bottle comapred to a retail price of £3.99 (or £4.99, can't remember which).
Anyway, ask for a discount for bulk where you buy from.
 
i bought some octane booster off a trader at york drag...a litre for a tenner no frills stuff i were happy with it.had my ibizza remapped for super unleded
 
My ten bottles of millers arrived this morning :D

Just been and added a full bottle to the tank when i filled up (5 litres in tank added 40 litres of petrol to full) It states a full bottle to 50 litres of fuel but cupra only holds 45litres.

Shouldn't be a problem should it?

Will do some airflow and timing pull logs tonight to compare, then do it again in a few weeks as its meant to take a full tankfulls to get max effect?

I used to mix a bottle with 38-40 litres of Optimax.
