Premium Unleaded for BA Falcon (Yes or No)

Hi All,

Any know if the BA Falcon's have a knock sensor?

Is there any point in running premium unleaded rather than standard unleaded in terms of performance? Does the engine actually take advantage of it?

Chris.

You talking about the 6cyl or V8?

To put it simply, the BA 6cyl does have a knock sensor and will benifit performance wise if PULP is used. The BA V8's don't have knock sensors and will not benifit performance wise if using PULP.

Any car regardless not having Knock Sensors or not will benefit from running a Premium Unleaded fuel.A knock sensor isn't there for performance gains.
Cheers Alex.

6cyl. So does the computer advance timing until it starts pinging - is this how it works? How does it know premium is being used?

Is there much difference in respect to performance comparing standard and premium?

Thanks
Chris.

What benefit tho? I have XT6. given PULP is 10% dearer will iget 10% better economy or a MARKED increase in performance (not just it feels a bit livelier maybe)

What does a knock sensor have to do with premium fuels? I thought it was there for exaclty as the name says, detecting a knock in the engine and shutting it own?

In terms of performance, The BA 6cyl will benifit performance wise by using PULP, only if you use it exclusively so that he EEC "gets used to it", and we're talking a very minimum increase in performance here, something similar to changing the standard air filter to a less restrictive one like a K&N. The BA V8's will not benifit performance wise. No you will not gain faster 0-100 or 1/4 mile times by using PULP in a BA XR8 unless your engine has been tuned for it by means of a chip or soon to be Boss Edit. Even then, it's not going to be much. The 290kW BA's are tuned for PULP already so no gains there anyway. Where did I say any car, regardless of having knock sensors or not will not benifit by using PULP? They will benifit in other areas, but in regards to a increase in power/performance, no they won't.

I use Optimax exclusively on my 220kW TS50, 'cause the engine was built for PULP. I once did fill up with normal Unleaded (Ex GF accidentally put in ULP) and the performance/power did drop. Couldn't go past 4000rpm without engine pinging. If I had a knock sensor it would have backed the timing to stop the pinging, but I'd still be down on power. Likewise, an engine with a knock sensor will adjust itself to the fuel being used. If it happens to be a higher octane rated PULP being used, the knock sensor will advance the timing at high rpm 'till pinging then back off slightly, thus giving a increase in performance. Knock sensor isn't there for performance gains? Yeah right!

Yes and, the knock sensor will help the EEC find the optimum timing for the fuel being used. This is the simple explanation.

No, not much at all. You'd be lucky to "feel" the difference. Use PULP and a bottle Octane booster in your 6cyl every time you fill up and you might notice something, but still nothing to jump up and down about.

10% better economy? you might, depending on how you drive and where you drive ie: City or Highway. 10% increase in performance? definitely not. You'd be lucky with 5%. PULP usually has benifits in areas such as keeping your fuel system/injectors clean, and in cars with knock sensors, a slight increase in performance. A cleaner fuel system helps with emissions, better mileage, etc..
