I run Redline SL1 at 60% and 20% olm in my wife’s Pilot.
Top tier fuel has plenty of necessary detergent in it already. the predominant issue with DI operation is not solvable by a "pour in the gasoline" wallet lightenerI've been told that injection cleaners do nothing for DI engines. But it seems to me that the Direct injectors have nozzles and spray patterns that need to be maintained. So wouldn't products like Sea Foam and Gumout help the direct injectors?
No. For example Normal Shell doesn’t have any detergents. Shell V-Power (Nitro) has enough additives only if you use it regular.Top tier fuel has plenty of necessary detergent in it already. the predominant issue with DI operation is not solvable by a "pour in the gasoline" wallet lightener
All gasoline has at least SOME detergent in it, Top Tier (& Shell V-Power) just have more. For example, BP/Amoco has their Invigorate detergent in all grades, but the (labeled Amoco Ultimate) premium has more detergent than the regular & plus grades. An overdose of Techron with V-Power has solved injector issues for me in the past, combined with a 400 mile+ highway run.No. For example Normal Shell doesn’t have any detergents.

I’ve tested Shell, BP etc in the EU. BP in their Ultimate and regular gasoline have the same level of amines. Shell only in V-Power/nitro. Anyway, it’s 40x-50x times less than BG or Techron.Shell regular unleaded in the USA is on the Top Tier list so it must have some cleaning agents...

I can test by the way of someone will send samples to Slovakia)In the US we have Top Tier that mandates any gas/petrol company advertising it have higher levels of detergents in ALL grades. But Premium grades V-Power and Exxon-Mobil's top octane may contain more....
