Got pings?

Just by chance I happened to fill up my 01'1150 GS with super unleaded at a VALERO gas station.
While doing my usual 2:45 pm grind up Willow Pass
I noticed an absence of pinging. Usually my motor pings on long mid throttle uphills. Especially when air temps are 90 Deg. F and above.
Try out a tankful. Of course I do not work for them or anything like that.

Never heard of VALERO Gas Stations-must not be an AZ thing...Butt I do know that the Experimental Aircraft Association (EAA) some years ago did a review of quality and consistency among national brand fuels for their members who build and operate aircraft that run on premium unleaded fuel, as opposed to the customary 100 octane Low lead (100LL).
I imagine "pinging" takes on a whole new meaning at 1000 feet AGL.
In the esteemed opinion of the EAA evaluators the most consistent fuel was Texaco with Chevron running a close second.
Since the study was released I've used Texaco Premium in 2K's, an R, and an F with satisfactory results.

pinging

I'm not familiar with Valero gas in the N'east, but a good remedy for pinging, (if you happen to get a shit tank of gas), is to add some Techron, made by Chevron, about $7 a bottle, to a tankful or two before filling up. This will remove any carbon deposits in your intake valves and improve throttle response. BMW recommends Shell SU 2000 (premium) to be used in their cage engines due to its almost non-existent content of carbon,...... I've had great luck with Texaco premium, and every once in awhile I like give my beast a high octane cocktail, so I squirt a tankful of Cam 2 racing fuel (104 octane) in,....... Yum-Yum......

A very pertinent caveat about the use of Techron, however...

Techron is basically naptha with a couple of stabilizing ingredients. While a great product it should be used sparingly-

I recommend using naptha/techron only in the last tankful before an anticipated oil change-in addition to loosing all the crud in your injectors it leaves deposits in your oil-causing it to breakdown and have irregularities of viscosity and thermoregulation.

pinging......

Myles,
Good point,..... I should have mentioned as well that its use should be minimal, I usually pour 2 oz. into an almost empty tank and then top it off, this being done every 3-5K mi.,...... so a bottle generally gets me through a riding season here in the N'east,..... I do between 18-24K mi. a season. Ride Safe, Ride Hard...... P.

Being an engineer in the petroleum business, I can't resist chiming in here.

Valero is a refinery operator and retailer from Texas that recently bought all the Exxon stations in N. Cal after Exxon became ExxonMobil and had to divest.

Techron is Chevron's cleaning additive for keeping intake tracks clean. It is okay to add extra, but easier to just buy Chevron gas. The Supreme gas has more Techron.

Octane rating refers to the resistance of gasoline to detonate (ping) in areas of the cylinder that haven't been reached yet by the flame front emanating from the spark plug. Higher octane does not mean more power, just more resistance to detonation.

Pinging tendency is worse when the engine in under high load or is hot. I am not sure altitude contributes because the fuel injection system on the GS compensates quite well. My R1100GS has always pinged a bit on hot days when I goose it on hills.

You should use the lowest octane gasoline that will work without pinging too badly. A little pinging once in a while is okay. You will save money this way.
