well after having the re map done running 97 ron from BP the car run fine with no pinking at all,
on the way home i filled up with £60 worth of OPTIMAX and god did she not like it, the car lost all power and jerked like a bitch for about 5 miles but after that all was hunky dory, got 31.9 MPG all the way home at 90 mph,
well friday night i had to pop out at 1am to get my ali from the station but i had no fuel in the car so i decided to just stick a £10 of normal 95 ron unleaded till i come accross a SHELL for more optimax, BIG MISTAKE, iv had to drive my car for around 60 miles with out putting my foot down or otherwise the poxy thing just jumped straight into LIMP MODE evry time.
phoned paul and he was bemused it was doing it as the map has bin on the car for 2 weeks now and iv not had any probs with all the time using the OPTIMAX in her, the only chnage iv made since going into LIMP MODE all the time was wen i stuck the £10 of 95 ron unleaded in.
iv give it some real stick with the OPTIMAX in her trying to get it into limp mode and nothing but a shot of 95 ron and its cripples the car,
so sunday afternoon while still running the shit 95 i come accross a TESCO which had the 99 RON unleaded in so with the fuel light on i stuck a full tank in at only 97.4p a gallon, so £49 later i set of,
pull out the garage WHACK straight into LIMP AGAIN. fuck me im getting sick of this, drove anothe 20 miles and she was still all over the shop, jerking pulling loosing power then, she settles, no more jerking nothing,
so i pull over turn the car off and restart her, pull away giving her some good revs and nail it in every gear and bugger me all is fine, not a bloody thing.
all the way home from my aunts in the evening GREAT no probs, but god can you feel the difference in the fuel, i even got 31MPG at 100 MPH all the way home with even dropping it down a peg from time to time to see if it went into LIMP MODE and nothing,
it feels more responsive better reving and even idle i think ?
from my own learning i will now never put 95 RON fuel in again, even 97 RON if i can help it but in emergances i will use it,
from now on i will only use this shit hot 99 RON from TESCOS with OPTIMAX in a close second,
iv never bin one to watch wat fuel i use but honestly how wrong was i.
sorry for the ramble.
