Testing Fuel Injectors: OE, Bosch, and Amazon - Royalty Auto

[rstsco]

In this previous video, he was troubleshooting misfires on a Mazda. At some point the injectors had been replaced with a set off Amazon. Ultimately, he replaced those with Bosch injectors which fixed the misfires. During the process, he bought an injector tester off Amazon and compared the spray patterns between the Bosch and Amazon injectors. The pattern differences were obvious.

In today's video, he continues playing with his new injector testing tool and compares the Amazon against the Bosch and an OE injector from Mazda. After playing with different modes, you can see that even the Bosch, which are working good in the car, have a relatively inferior spray pattern compared to the OE.

Yes I was thinking of getting one of those testers as they're available pretty cheap now. Nice tool to have around the shop.

I can't watch this guy anymore, just like TCCN and others. He exposed his ignorance on a video with a BMW that destroyed it's transfer case shortly after they had serviced it. He chalked it up to using non-OEM fluid which most of us know and understand is definitely not true.

Anyway, it's nice to have someone online to show and tell, better if they're experienced and talk from such.

He said the cost was ~$650.

Most on BITOG are not their target audience. Overall, TCCN and Royalty do a pretty good job educating the uninformed. The older Sherwood does know how to use his scopes. Many techs don't. Personally, I find the younger Sherwood annoying.

When listening to them, I typically change the speed to 1.5x and wear headphones while doing other work around the house. The videos are usually 20-30 minutes at normal speed, so I have 12-15 minutes to work on whatever I'm doing before finding the next video.

The machine is good enough for what he wants but it is not a good machine on the other hand it is not 10K either. Some one should tell him the spec for testing non gdi injectors is 43.5 psi higher or lower effects the flow rate and spray pattern. He should know never buy injectors from Amazon or ebay, the Bosch could be a knock off there are loads of them out there, I have done too many Bosch injectors to count over the years and have not had a bad new one but have seen some fakes.

 

[KGMtech]

Sherwood is very personable, but not the same league of mechanic as SMA or PHAD by far. The injector test is nice eye candy, and $650 is not bad.

 

[JGmazda]

I found the video (and Sherwood) to be very knowledgeable. I think we all can be over-critical at times. It's very interesting to see aftermarket parts and their sub-par performance. Thanks OP for posting this.

The unit I saw looked similar but was around $400 CDN on Amazon so, $250 USD?

As you note, those two in a league of their own. Also watched a Royalty vid on how he determined the cost/pricing of the work at his shops. Based on that, his overhead costs are to say the least, very high.

I dealt with this on end on my Cavalier. Just see my previous posts. I spent way too much on oem fuel injectors from pull n pay Cavaliers. My dad ordered a set from Amazon and they were absolute garbage. They did somehow barely pass emissions but died at red lights . I got a deal from a place in Georgia on oem delcos but still have a slight tick and exhaust crackle.

They have a brand new shop, it's well equipped. It's not like having a 2 bay 50 year old building.

Well, this guy got a $650 machine, is on YouTube, and is personable.

If I want opinions on injectors, I would rather have a guy with a $10,000 machine, and decades of experience rebuilding injectors for a living, than a YouTuber with relatively little experience.

What’s fascinating, is that you place your faith in a YouTube personality, and completely ignore the guy with decades of experience, who just posted above.

Well aware, doesn't change my observation about his overhead costs. Safe to say, if I was interested too rich for my blood. In comparison, I expect the other two noted by @KGMtech, significantly more reasonable and a reason I replied directly to his comment. That in addition to them being superior diagnosticians, imo.

 

[KrisZ]

People are easily impressed I guess. So this YouTube mechanic complains about cheap Amazon injectors, yet bought a cheap Amazon fuel injector tester to “test” the injectors.
Yup, it logically totally follows .

This guy is a good entertainer and a story teller though, so this “tester” is meant for entertainment purposes only and will add to his story telling, simple as that.

Tell him but they won't care. They're getting clicks, as evidenced by how often these clowns are referenced in this very forum.

They don't care if they're clowns (or their overhead is high) -- once you're making $ from content, then you just need content. Accuracy is irrelevant. Very, very few can resist this.

 

[CrackerG]

Every tester sold by Amazon thru his YouTube link is a $$ smile on his face. Not impressed.

You people are so far off into the weeds with Sherwood, it's not even funny.

First off, the owner of the Mazda CX-9 (with the Ford V-6 engine) bought and installed the Amazon fuel injectors himself, while trying to self diagnose and repair a misfire issue with the CX-9. Sherwood DID NOT buy and install the Amazon injectors.
Turns out that the misfire was actually caused by a bad ignition coil on Cylinder 1, combined with a full set of bad Amazon spark plugs, that the Owner also installed himself. The spark plugs actually were for a Ford F-150, so completely wrong application.

Sherwood fixed the misfire by replacing the 1 bad coil, and the 6 garbage spark plugs, and then the next thing up was to fix the overly rich mixture with the -15 fuel trims. That lead to the replacement of the 6 Amazon fuel injectors with the Bosch units.

That lead to him wanting to show the difference in how much fuel the Amazon injectors are injecting in comparison to the Bosch, and eventually the OEM, which lead to him buying a cheap fuel injector tester, simply for the fun of it. He's not going into the Fuel Injector repairing business, and he's not a competitor to Trav, so ya'll just need to stop with that nonsense.

To @Trav , those injectors were supposed to have been from the Mazda CX-9 with the Ford V-6, so not a DFI engine, so I'm not sure why you're commenting about DFI pressures, unless you noticed that the injectors he had mounted to the machine were different from the Mazda application...

As for those of you complaining about how he runs his shop or his YouTube channel...
Let's see you do better on both fronts.
The man works, his entire team works, and he's still able to generate a steady flow of content.
Take your complaints about how much overhead his shop has, or how you don't like him as much as someone else on the internet to your bathroom, and flush them down your toilet.

As far as the BMW front axle that died a horrible death, his shop ate the cost of a new front axle being installed in the customers car.
What more do you want?
The axle supposedly didn't have any issues when it came into the shop, and they did a drain and fill on it, and then a couple days later, there's metal in the axle. If it wasn't a failure of the lubricant that caused the death of the axle, what do YOU think caused the failure? Are you willing to buy a copy of the car, and change the fluids yourself, and post the results to see if the axle fails on a different car under the same circumstances?
That's a weird grudge to hold for so long about 1 video.

 

[martinq]

Thanks for the info and details. I might watch it but the last two times I tried it was hard to watch with my bias.

"If it wasn't a failure of the lubricant that caused the death of the axle, what do YOU think caused the failure?"

According to those in the know and experienced with this BMW transfer case / application, It's a recall / class-action waiting to happen. Maybe by now it already has?

Yikes, I guess we touched a nerve

I think it's more the amount of criticism by those who obviously haven't watched the video.

Hitting a nerve may be spot on, but it's the nerve of those who do not like Royalty Auto videos... similar to those critical of Lake Speed Jr's videos without watching them, either.

I agree. I personally like his channel and watch it a lot. For those that say he is not experienced do not know what they are talking about. He has been a mechanic since the late 80's so he knows quite a bit. I agree his son behind the camera can be irritating but I find the content on the channel pretty useful.
