Testing Fuel Injectors: OE, Bosch, and Amazon - Royalty Auto
- Thread starter rstsco
- Start date
Please read my post again, I said..
Even though the car may spec higher or lower psi OE spec injectors are tested at 43.5 regardless. In the spec sheets they don't say this part# for Ford whatever 43.5 but for Chevrolet test at 50 psi. Some HIPO injectors like ID which are Bosch performance, etc may indeed spec higher testing pressure.
So, if I go to Home Depot and buy a $60 level instead of a $500 level.... My carpentry and project are going to be less level and plumb?
Anyone with "eyes" can see the difference in the injector spray-patterns with the different manufacturers. And you're commenting - "He's on YouTube and has relatively "little experience"....???
Really? Are you just throwing darts at the wall?? You obviously don't know the man or his experience and qualifications. - Regardless of being on YouTube or not.
Wow.... Just wow.
Right-Sot-On! I never imagined so many haters.... With NOTHING but time to write how bad this guy's channel and methodology supposedly is.
Did ya'll miss the core message??? Yup..... apparently so.
Au contraire - you don’t know anything about the person with whom he is being compared.
@Trav is far more experienced and capable than this guy and you still have no idea.
All I need to know about injectors has come from my talking with him. If I had a question, I know where to direct it.
Keep worshipping YouTubers all you like, I’ll stick with an actual expert.
@Astro14 - I highly respect your opinions, and don't know @Trav, but you do and speak highly of him, therefore would trust him implicitly. Not all of us have direct access to experts, therefore we do the best we can with what's available.
Sherwood admitted he doesn't know how to use the machine, the instructions weren't clear (or non-existent), and just started mashing buttons to see what he can see.
I think where this whole thread has diverged is in regards to the overall message: be careful of the parts you're putting on/in your car. This message is not new, especially for us on BITOG, but I thought Royalty Auto's video did a fair representation of showing a layperson, such as myself, why this is true.
Had I known this thread was going to devolve into what it has, I'd have not posted what could possibly be useful infomation to some on this site. It's the same reason I no longer am the first person to post LSJR's videos. The content doesn't matter (good and/or bad), only the messenger.
Kindest regards.
And you, clearly, missed the core point I was making.
This guy discovered the obvious.
You missed the point: we have a true subject matter expert on the forum and in this thread.
He already knew what this guy “discovered”.
That’s significant, important and relevant and you have confused it with “hate”.
Your inability to see where genuine expertise exists against the backdrop of flashy presentation generated feedback, not hate.
Clearly I have. My apologies.
I thought your comments have been spot on - no worries.
Look, if you didn’t know much about injectors, then, the posted video was likely a surprise - and informative.
But I didn’t learn about injectors from a video - I learned about them from making mistakes in the past, but more importantly, talking with a real expert, who I met on BITOG.
Here’s an analogy of what’s happening in this thread - if you met a Boy Scout, with the First Aid Merit Badge, who taught you something new about emergency response, that would be cool.
But if you were intently listening to the Boy Scout, while sitting next to the Head of Emergency Surgery at Barnes Jewish Hospital, and ignoring that surgeon - then you’re missing out on an opportunity.
And that is exactly what is happening here - only I am called a “hater” for pointing out who is sitting in on the thread.
Core message of every YouTuber and social media personality:
“Hit that subscribe and notification buttons!!”
Folks, as I look back over the thread, I have a couple of thoughts.
What @rstsco discovered in this video, is actually unknown by a lot of people.
Not everybody knows, though I think they should, that aftermarket injectors have poor patterns.
Fewer people know, and this was a good point in the video, that even good quality injectors from a company like Bosch, may not have a pattern optimized for the application the way that OEM injectors are optimized.
Now, I feel like I started a counter-productive side track by pointing out a much more expert source on the topic of injectors, one of our very own from whom I have learned a lot. I am not one to let go of a point easily (see the antique car registration thread), but that side track has detracted from the merit of the video in pointing out, via video, a couple of valuable points.
So, sorry for taking things off topic.
Now, when @Trav talks about injectors, it should be like that old E.F. Hutton commercial in which everybody stops talking and turns their head to listen.

yeah, younger sherwood is really annoying. Shut up! LOL
Yep, then get paid by the click, and ring the register, nice!!
You're correct - I don't know anything about this person - @Trav. From what I've read in this thread, he's the cat's meow when it comes to knowledge about fuel injectors.
And... apparently, ALL your fuel injector knowledge has come from speaking with him. Wonderful. I'm happy you found a source you can rely-on.
When I started reading this thread, it was about the YouTube video. After "worshiping" this Youtuber (amongst others) and clearing missing his hidden financial reasons for posting it, I've come to the conclusion that his knowledge, expertise, education, work history and YouTube practices are wildly questionable.
I'm kicking myself at this point. How could I be so gullible?? It's right there in the video! His cheap fuel injector testing machine and clear lack of "fuel injector testing" procedures is clearly evident. I totally missed it the first time I watched his video. But now??? So clear! How could ANYONE trust this man and his message??
Hopefully, I too will be able to consult with @Trav and ask him for more relevant and accurate fuel injector knowledge.
Until then... I will try very hard to eradicate Sherwood's advice about using aftermarket fuel injectors. I'll try. And I'll try not to watch (Worship) all those fake backwoods shyster low-education mechanics that populate the YouTube universe.
We have many very well respected members here because of their contribution to this forum over the years. People can interact with them, almost in real time and get their expertise opinions. Their assessments are usually very accurate, hence they have a high reputation here, not because their posts sound good and appeal to the general consensus, but because their posts are usually spot on and their expertise has helped many people troubleshoot their vehicles.
You're just a consumer of carefully crafted videos and a personality which may or may not reflect the reality. You only know what this youtuber chooses to show the audience and his videos are meant for mass consumption and mass appeal. By the very nature, it will lack a lot of the techincal aspects many of us are looking for in an "expert". Hence the criticisms.
In this day and age there is information everywhere on the internet whether it is here, some vehicle or repair specific forums, Youtube, TikTok, etc. You have to figure out if what is being taught or said is valid or not based on your own experience or the information given by multiple people that tend to reaffirm what others are saying.
I would never base information on just one source no matter how knowledgeable someone seems. I have learned a lot of things over the years by watching various Youtube mechanics and used their information to fix my own vehicles and those of others. Some have good information and others not so much. I have used some of the information here to do the same thing. A lot of the stuff that I know I just figured it out on my own by trial and error.
For some people, watching a video helps them more than someone trying to explain it to them and that can be a limitation of the various forums out there or even the paper service manuals that people use.
