Hi everyone,
My first post, just wanted to give a heads up. Too much Redline or Techron (hard to say which, bombarded the fuel system with both) may wear out your o rings. Mine became very brittle on the fuel pressure regulator, fuel sprayed all over my engine.. I was able to crack them pretty easily by hand once they were taken out..
It leaked from top first, so that was replaced, but then a week later, the lower one went too and this all started about a week or two after the following steps:
Full tank, no additives (yet) just Shell V-Power NiTRO+
Once at 1/2 tank:
Two bottles of STP Super Concentrated Fuel Injector Cleaner (10.5oz total)
Jumped on it HARD several times (Italian tune-ups hehe)
Run until gas light comes on, re-fill.
Once at 1/2 tank:
Gumout Regane Complete Fuel System Cleaner (12oz)
More Italian tune-ups
Run until gas light comes on, re-fill
Once at 1/4 tank of gas:
1 bottle of Redline SI-1 (15oz)
More Italian tune-ups
Run until gas light comes on, re-fill
Everything seemed fine so I kept going with trying out these additives, I probably should have stopped here...
Fill tank up, keep jumping on it really hard, neutral drops, redlining it, just really beating the crap out of this thing..
Once on 1/8th tank of gas, yes AN EIGHTH:
2 bottles of Redline SI-1 (30oz, SUPER HIGH CONCENTRATION)
1 bottle of Lucas Octane Boost (15oz)
More Italian tune-ups.... Car ran EXTREMELY ROUGH, shaking away, was worried the car was actually going to going stall, kept the throttle down and powered through, steering wheel vibrating away...
I actually idled the car at the gas station until it ran out of gas to really push everything through once I had a feeling it could run out any second.
Fill tank up, resume the Italian tune-ups!
Once on 1/4 tank of gas: 2 bottles of Techron (24oz)
Italian tune-ups until empty
Now here's the thing.. Several fill-ups later, no more fuel additives after the Techron, THAT'S when my o rings started failing.. Now.. I'm not 100% certain when EXACTLY the leak started because I did smell some gas occasionally for awhile before I actually saw any leaking due to it being such a small leak initially, and the fuel regulator in a 2001 Maxima is quite tucked away. Once I spotted it, the fuel regulator looked like a leaky garden hose and the top of the engine was all wet, it got pretty bad and a potential fire hazard..
I know I used more than recommended, but I just want to let people know that there may be a risk with overdoing the fuel system cleaners..
ON THE BRIGHT SIDE: The P0430 code has never come back! My car sat for about 4 1/2 years being redone (lots of body work, fabrication, welding, engine work, etc) so I just wanted to try and flush everything out. That code ever since I bought the car like 9 years ago would pop up occasionally. Now, there's a trick to get the P0430 code to disappear by moving the O2 sensor back a foot or two away from the front one, but this only worked temporarily. After all these additives, the car is actually incredibly responsive and it certainly did something.
165K miles on this Maxima, looks and drives like a brand new car
If you are going to go nuts with Techron and Redline, please keep an eye on your o rings! I believe if they were all 100% silicone, they wouldn't crack or warp but it'd be more expensive to manufacture.
I don't think I'll be adding anything to my tank except premium gas for awhile.
Cheers!
