Mixing E85 And U98

[PureBassHavoc]

I have been reading some forums of people mixing u98 and e85. I have read the effects of 85 on fuel lines etc but only when running 100% e85. But I was looking at running maybe 70% u98 and 30% e85 or maybe even more 98 comapred to 85. My reasoning is that with the high prices of 98 mixing 85 would be a bit cheaper to run. I drive a 2003 BA XR6 with a redback cat-back exhaust. Open to all ideas

Yes you can mix them at the right quantities (I have no idea what they are)

You can get a 100octane rating at the right mixture

But it is only worth it if your car is tuned to run on that mixture

Overall a pain in the ass, better off having a 98 tune or an E85 tune

have you checked the price of E85 in your area?

It is dearer here than 98 and it gets used at a faster rate, so makes it more expensive to run on it and that's not even considering the cost of tuning and upgrades

Think I might stick with 98 to avoid all those troubkes

98 Vs P100

Why bother on a N/A is more the point

[BenDoCo]

^^. Agreed

Since it's n/a, what you really need to do is install a 100 shot

Burn it and buy a turbo.

If you want the same ratio of ethanol to regular petrol as was in the old United P100 (10% ethanol, 90% unleaded) you need 88.25% unleaded to 11.75% E85. It's only worth running this if you have a tune that makes the most of the ethanol in the fuel.

On an N/A car, even with a tune it is unlikely to be worth it. On a car with forced induction it can be useful to gain some extra power at little extra cost.
