You've never seen 91 octane? https://www.fueleconomy.gov/feg/octane.shtml Ethanol free around my area at various stations is all either 90 or 91.
Many car manuals will say premium 91+ or reduced performance may be experienced aka knock sensor pulls timing.
Ok guess my car happened over 4 tanks of the exact same driving to drop 25% mpg. Then oddly enough gain it back ever since. You talk about science yet mention nothing to back that up. Besides likely being someone on the selling corn end of ethanol. A stock flex fuel car does not gain mpg or...
High content ethanol is incompatible with most cleaner additives used in gasoline. That's why flex/e85 has none currently at the pumps, at best you will just be wasting money. E85 is a waste of time anyhow unless your getting it free the mpg drop offsets the now minor price difference. Now if...
The pea would only wash off the valves if it as more are doing a 2nd traditional (port) injection system. This allows the fuel to go over the valves and clean them as it had before di. Let it go long enough and some di can require specialized blasting to clean the carbon off using walnut or...
Sunoco at some stations sells/sold cam2 Cam 2 available in 110, 112, and 116 octane leaded. When gas was around $1.00-$1.50 a gallon it was around $3.50 at the one my town had. They do not use lead(tetraethyl) in their unleaded gasoline which should go without saying. Though it appears not...
Little bit older thread but so are crown Vic's I'm ordering the police ones. There are a few physical differences but the tolerances allowed appear to be tighter. Police rotors meet the SAE standard for tensile strength, guaranteeing structural integrity and maximum service life. A turned finish...
I normally used stoners cleaner but have griots now, don't see much difference. Though I will say expect to clean glass twice minimum if you really want it clear. There's most always a little residue left that likes to catch light or fog faster more so if smoking or you've detailed and there's...
I hadn't tried paste from them but the 845 I believe could be one the easiest removal products I've used. Granted I usually had applied it just before winter and use cleaner in the summer before application.

Rather odd advice to ignore what your vehicle...
WW and the others making a similar product are/were created to run in race cars where glycol was a no-no. Though it does provide a possible advantage even using coolant. However the way many measure it's effectiveness is flawed i.e. running cooler. Most cars unless you install one measure...
If there's no activated carbon it wouldn't be as much a deal. But I've seen this on home hepa filters installed wrong and the charcoal got all over the blower.
Yeah $10 or 20 every year or 2 is not much besides keeping crap from getting drawn in. You can knock crap out but there's still a lot of small particles pulled into the material you can't get out. Eventually the charcoal does become ineffective esp important if you've got allergies. Any little...
Vinyl covered leather like on many of the cars is still leather but needs treated and much different. It needs to be small enough molecules to get down through the "pores" to the leather. Something like a thick creme could sit there till the rapture and not do much good. A soft natural hair nail...
