So my car has 60k miles and I have had to replace the high pressure fuel pump twice now, today being the second.. anyone else having bad luck with them? And how can I prevent it.. it has a stock tune..

 

What oil are you running and what was the code causing the need for a replacement?

 

Low fuel pressure I forget the code number.. and currently 5w30 full synthetic royal purple, only because I got a case (6) 5qt jugs of it for free.. so I've been using that for about 4 months.. 2 oil changes

 

Did the car also run like crap with the code? Because there is a code for lack of fuel pressure during WOT

 

I hope ur running 4718 certified royal purple, if not drain it out of ur car right now and get proper oil. I destroyed a cam lobe using royal purple 5w30 full synthetic but not 4718 certified. engine started ticking a week after I put it in. the result, new motor.

 

Ive also heard bad things about royal purple. Just use mobil 1.

 

Yes it's the GM Cert stuff I checked the bottles.. and yes the car ran like dog crap.. stutti ring and wouldn't Rev past like 2500.. the new pump fixed it but this has happened with 2 pumps.. I can't believe it

 

Expensive as pumps too. Just buy an aftermarket pump thats stronger you dont need a tune to run it iirc

 

Like others have said, I would never run royal purple again even if someone paid me. About a week after putting the GM certified stuff, I wound up with a pretty substantial hole in my block. Before that it caused some funky things to happen with the car.

 

There are no aftermarket stronger pumps for the LNF high pressure fuel pumps

 

YET. HPFPupgrade is currently testing one they're making for us

 

its interesting how u can search google and find so many storys from so many people with different cars, mostly boosted, that have pretty much the same storys as us. I would never touch that crap. I use mobile 1 or even better penzoil platinum. both have worked awesome in my car.

 

u know if I was planning on getting say a new motor that was built, I would purposely put royal purple in my current one and drive around for a month just to prove what **** it is, and document it with video.
