daytona600 0 Posted June 16, 2005 Hi all. Just joined the forum after picking up my VR6 on Sunday. Always wanted one! I am concerned that I may have filled up with the wrong petrol. I filled her up with regular unleaded. Should I be using the higher octane (more expensive) flavour? If so could I have caused damage to the engine?

Jim 2 Posted June 16, 2005 Welcome to the forum! Regular 95RON unleaded will work fine, but nine out of ten Corrado owners prefer super unleaded or BP Ultimate / Shell Optimax :) Quote Share this post Link to post Share on other sites
Ady_G 0 Posted June 16, 2005 Shell optimax is 98 ron as recomended on the inside of the fuel filler flap, it will run on 95 ron normal unleaded, but isn't quite as responsive. But don't go to supermarkets for fuel I always use optimax Cheers and have fun with the VR6 Ady Quote Share this post Link to post Share on other sites
daytona600 0 Posted June 16, 2005 Thanks Jim, will it run smoother, be faster? Is it worth the extra cost? Sorry, so many questions (newbie) Quote Share this post Link to post Share on other sites
daytona600 0 Posted June 16, 2005 Thanks Ady, you answered my reply. I didn't buy the car for economy so what the hell. Quote Share this post Link to post Share on other sites
Walesy 0 Posted June 16, 2005 i always find that cars run smoother on 98.. Quote Share this post Link to post Share on other sites
Jim 2 Posted June 16, 2005 Yeah the car runs smoother and more responsive on the higher RON fuels, definately. I pretty much used to run my G60 on Ultimate all the time, wherever my wallet allowed! Quote Share this post Link to post Share on other sites
andy 0 Posted June 16, 2005 Supermarket fuels are fine, I always run my VR6 on Sainsburys super (97 RON) its higher octane than standard unleaded and massively cheaper than the likes of Optimax. Quote Share this post Link to post Share on other sites
Stan 24v 0 Posted June 16, 2005 Cant you get additives to add to normal 95RON to increase it???? Quote Share this post Link to post Share on other sites
Ady_G 0 Posted June 16, 2005 I thought that although optimax was more expensive, it burnt more efficiently, so it might end up costing you the same, but you go further on a tank, and faster. I only did 4000 miles in the last year though so fuel costs aren't that costly Ady Quote Share this post Link to post Share on other sites
RW1 0 Posted June 16, 2005 VR6 ECU adjusts auto matically for fuelling with 95 - 99 RON. Difference in power though acorss the rev range. Generally about a 3 - 4% power loss between 98RON and 95RON at peak revs (5,800rpm) and proportionally below that. Quote Share this post Link to post Share on other sites
