Top Tier gas
Anyone have any information or knowledge relative to top tier gas vs. non top tier gas of the same octane? Watched a program where the inside of the cylinder was photographed after several applications of concentrated Chevron cleaner.
there was little or no difference.
I realize the difference may be greater when using top tier gas from the beginning. Honda, Mercedes and others recommend top tier. Costco only sells top tier. Always look for top tier or a good brand name.
Is the effort worth it? I have an LS460.

So, how do you know if your getting top tier gas ? So If I go to a Shell or Sunoco (both on the list) with a Haji-Mart attached to it, am I getting TRUE top tier gas ?
I always go to a good brand gas station, Normally Shell or Sunoco 99% of the time...

I think "Top Tier Gas" is simply name brand gas. Unfortunately, gas stations get their gas from refining distributors and you never really know what you're getting. If you're worried, though, get the name brand and use a can of Techron every thousand miles.

I always use top tier. Once asked a tanker driver who was dropping Chervon into the tanks about the additive- He said Chevron was extremely steadfast on all their gas has their additive package added before the truck leaves it's terminal (Ft. Lauderdale that day)-I believe the others do the same. I've heard from station owners that the gas companies will come by occasionally and test the fuel to make sure it's their gas-like it's tagged with that particular branded detergent. Costco adds its own detergent package into the ground tank when the tanker arrives at the store according the attendant at the pumps.

I normally fill up Costco gas for all my cars. I try to avoid going during busy hours or when the tanker is there. If I couldn't make it to Costco, then I'd fill up at BP or Shell. 93 Octane over here.

Difference for top tier gas is with the additives. All 4 cars in my family only use Shell high Octane gas. Also fill up where the turn over of gas is frequent to get the fresh gas and proper one when season changes.

All the gas comes from the same pipeline. All the tank-trucks pull from the same refineries. As stated earlier, the difference is the additive. What’s more important is which retailer you buy from i.e. the age of the retailer. Newer ones will have new equipment, filters, pumps, underground tanks made of fiberglass, etc. Old ones can have old steel tanks, corrosion, no filters, etc. Put a can of additive every few thousands of miles and you’ll be fine. And don’t fall into the ‘high-octane’ myth. New cars’ computers will automatically adjust to lower octane settings and your car will be fine. Also, I wouldn’t have believed it unless I saw it with my own eyes, but certain markets have oil packagers/blenders (whom the oil companies hire to bottle/package oil on their behalf) and it is often the EXACT same oil going into the different bottles. No additive difference or anything like that... once saw twelve different branded bottles (Castroll, Pennzoil, BP, Havoline, etc) with the exact same petroleum 10w-30 being dispensed into different branded bottles during a tour of a packager. Really fascinating what role marketing can play!

Today's engine oil is rather chemical soup of many different combined purpose and on top of that there is old dino juice based vs. synthetic. Of course it is each individual driver's choice what to use. There are cars like mediocre engine or ones designed for peak performance to get last drop of horse power and torque with precision engineering. Also driving style, driving environment(climate, road condition, etc.) I just treat my car according to the owner's manual. When trade-in time comes I get top dollar towards to new car of my choice. If I sell my old car privately it does not even take two days, the minute I ran an ad. buyer is at my door(little exaggerated). Kids in my neighbor beg me to sell our old car to them. They often borrow my tools such as OBD scanner, TPMS tool, VAG VCDS tool, special sockets, stuff like that.

There is some difference in crude oil where it comes from. Like heavy crude oil, light sweet crude oil. Some heavy crude oil has high Sulpher contents, etc. Near where I live there is an old oil field which produced lot of sweet crude oil to help fight the WW II. Old timers often talk about the stuff out of ground was so light they could fill their gas tank with it to run their cars.
