Well, I bought a bottle of Redline fuel system today ($17.99) and will do like the directions say. Run the tank to close to empty and add 20 gallons (will use shell 93 octane) gas. I looked at some videos on You Tube. Anyone see these motor internals on these videos? They look like these people change their oil every 30K miles at best. I know at 51K on my truck it doesn't look like that doing oil changes every 5K.
Anyway, I'll be putting in the Redline in the tank this weekend and per the directions I'll give it another bottle at the 3K mark on my recent oil change I did last week. Sound good guys?
Good luck, and please report your findings.
For what it's worth, I've tried the single jug of RL Si-1 per tank on a couple of vehicles, several times in the past with no noticeable results.
After experimenting with higher concentrations, I've observed less acceleration delay and a perceived performance improvement that makes me want to drive my truck more often.
I'm still riding the wave from my Springtime application of 1 bottle of RL Si-1.
Like some previous years, I haven't yet switched back to 87 octane, still enjoying the performance with 91.
The regular 87 octane is selling up here for about $1.75 to $1.80 per litre.
About 3.8 litres/US gallon or $6.65 to $6.84/gallon.
If the top tier 91 octane is only $2.00 per litre or $7.60/US gallon, I may as well enjoy the driving more.
If I were to take a long trip, I'd likely choose the 87 octane and perform another Si-1 cleanse.
Also, there is this loudmouth Scotty Kilmer who bad mouths everything including fuel system cleaners and other products. I think this guy even hates the sun when it rises in the morning.
Most of us are familiar with Scotty K and his silliness.
He has become like clickbait for those who seek drama.
I would take anything he says with a large block of salt.
