Petrol Question

[Guest TonyH]

I haven't tried PULP yet. I was wondering if you can get better economy with it and if so if its enough to offset the extra cost.

i havent tried normal unleaded.. but i know a few other guys have here.. anyone help?

I have tried both regularly, and no there is no difference in economy.

Interestingly there is hardly any performance difference either, so I plan to mix the different fuel types depending on availability.

Sure PULP will result in slightly higher performance at full throttle, but in everyday driving, how many of us go there too often!! - Costs too many points! :(

Agree with evrything ninka said.

l use Shell fuel mostly, alternating between ULP and Optimax. Dont notice a difference in economy or power.

You certainly wont get the 8c a litre back in improved economy. Its more important to ensure you buy fuel from a major (Shell, BP etc) than whether its ULP or PULP IMO.

I read an interesting article here. Lot of other interesting facts about cars and stuff in general.

Thanks guys for your help. I think I'll be sticking with ULP. that's a very interesting website mvec. Very informative.

a fleet person who got my car rang ford up about this, because they dont want to pay for premium, ford said for one week of every month to use premium and the others to use regular, something to do with clearing out the engine, I'm not positive on the reason, but that's what ford said to do and I would recommend following that idea. What im doing is the first week of every month is premium, the other weeks are regular.

Best advice,

Alternate your go juice!!

2-3 tanks of ULP to 1 tank of PULP. the odd injector cleaner thrown in every now and then.

Most PULP come with detergent additives that clean out carbon deposits - that's probably the reason for occassionally running premium

I'll bite.

I almost agree with everything ninka said. There is no economy improvement generally.

Except 1 point. Performance. You might say I can't feel a difference, but dyno after dyno will show a difference by using a fuel with increased ron. But let me ask this. When you say you use ULP instead of Optimax, do you mean premium or regular ULP? In my experience, you will see a difference between 91-92ron ULP and the like of 98 ron Uptimax. Make a bigger diff too if you add in some methyl benzine!

Optimax, Ultimate and Synergy 8000 all use different cleaning properties and are a denser fuel than normal ULP, so IMHO an extra 10c (here in NSW) is worth it.

Also, if the ECU is self learning to a point, then adding 98 to a 1/4 tank of regular ULP is not going to allow your car to perform as soon as you pull out of the servo. You have to wait for it to learn, or reset it so it can adjust the timing quicker. I do not know what type of ECU is in the new XR6T, or whether it allows the timing to change...
