BP gasoline with invigorate

I also vote in favor of gas wars.

I'd be good with Beef wars....steaks and ground beef are ridic.

Exxon was half the other two in the study I saw. Regional differences? I dunno.

This isn't the video I saw but you were right about Shell and BP premium and I was right about Exxon regular according to this video.
I use only regular and a lot of Sunoco, Valero and Shell because they are convenient but if I have a choice I try to use Exxon.

I use what ever gas is on sale. Period ( my cars only require 87 ). Once in a blue moon I'll throw in 93 if on sale. Noticed it burns much faster than 87. So, screw that . 87 is 87. They add the additives at the station or the depot. My bro-in-low trucks gas and that's how it works. I throw in a bottle of Chevron and dry gas every now and again to clean things up, and get moisture out. Only use the red bottle of HEET. That is the real isopropryl alcohol that removes moisture. The yellow bottle does squat. This ethanol fuel sux anyway. Now I heard they want to increase the percentage. GREAT More black tailpipes. Garbage corn liquor they're feeding us. LOL

In reality, 93 octane burns slower, so that it doesn't ignite before TDC or spark.

I don't care much about TT. I just try to remember who gets new tanks and how clean they keep their facility. On 2 recent trips I filled up with BP regular on the first trip and got 33.5 calculated and on a second roadtrip I got a fillup at local Marathon and got 31,5 calculated. Neither fillup was very scientific but I just fill till the pump shuts off and wait 20 or 30 seconds and fill till pump quits again.

I've seen that linked here before. The issue I have with it is it's so old that the data is outdated. For example, Citgo is now Top Tier so it's 87 levels have to meet the TT minimum so it's surely higher than the Speedway EPA minimum 87 octane.

Here's is what I'm personally doing. I do try to get the cheapest gas and try to get top tier. Costco usually fits both but on some on my longer routes, BP/Amoco fits that. I believe that they just decided to stop paying the fee to TT and kept their detergent levels the same. It would be false advertising for them to claim to meet the standards. It also seems like they've always advertised having better gas, especially in their premium version which is something I don't recall cheaper stations like Speedway doing. I don't use enough Amoco/BP for it to affect my vehicles as I do mostly TT (especially Costco).

I also have a different set of logic for my two cars. For my Taurus, I used to get the cheapest gas for years from Sam's, Speedway whenever. Now I've decided I only get TT for it and some BP/Amoco. I try to get Costco bc they claim to have 5x Top Tier minimum (and they happen to be cheapest with Sam's). My logic is I neglected it for so long that I might as well maximize the detergent levels (or at least have better than EPA standards with TT).

With my 300k plus TL, I still try to do TT but I'm more willing to put in Sam's or Speedway if cheaper/more convenient. My friend put only premium in it until I bought it from him 50k miles ago. Even if he was using cheap stuff like Speedway, the premium there has higher detergent levels (as seen in that news segment). I figure it can afford the occasional cheap non TT gas in it. Also I put 87 in it as I'm not paying $1-1.10 more for premium for this old clunkers when the extra mile or two I get per gallon from 93 octane will never make up for the cost difference. (I sometimes go to Iowa and the premium was only 30 cents more. I'll get premium for that "deal" when I'm there).

It doesn't burn any slower nor any faster, nor is it cooler nor hotter. It resists pre-ignition better.

All my cars live on 87 and we have a rather large selection of different gas stations brands here in Atlanta. Chevron/Texaco is my go-to but will gladly use BP or Exxon as backup.

My DTS with the Northstar V8 is the only one I “treat” with Shell 93 V-Power Nitro as it’s mostly a highway cruiser (we take lots of road trips) and it consistently turns in 25 mpg which I don’t think I could hope for any better from that engine. Running great with 150k on the clock.
