BG auto products.

[Dave Lehnert]

A lot of opinions but like to hear from a auto tech or someone in the know.

Are BG additives worth the money? I'm not big on additives other than injector cleaner.

My trusted repair shop I have used for years and years recommended BG PM109 and MOA after I did have a control valve solenoid (intake and exhaust) replaced because it was plugged up. A common problem for my SUV.
The dealer AWAYS push BG stuff. I never trusted the dealer so never had it done. My trusted shop never pushes it but did recommend it this time. Again I trust them 100% so I gave the go ahead.

Just like to know with my new car purchase planed in a year and a half if I should make it a regular part of my maintenance? Just like a mechanic point of view who is not selling me the product or anyone who has regularly used it and noticed a difference.

Other than in some very specific situations with specific vehicles/engines, I doubt that there is much benefit to using additives other than to the retailer and the manufacturer. If you are using a good quality, "top tier" fuel, there's already plenty of detergents and other things in the fuel, so it would be very surprising to me that adding something else would have much, if any effect, including "targeting" specific parts. Good fuel and regular maintenance per the manufacturer schedule or sooner should do the job.

[Ronald Blue]

I'm inclined to agree with Jim. Unless your driving conditions are unique I'm doubtful you would see any benefit to additives. Usually they are a hail mary to try to avoid more extensive internal work. In my opinion/experience the hardest thing on any engine is not being driven long enough to reach full operating temperature. Two blocks to the store 3 times a week but never any drives of at least a few miles to get all components fully warmed up and moisture burnt out. We've probably all saw vehicles that they start them up and literally have water running out the exhaust almost immediately even in warm weather. That's a result of not getting hot enough to burn the moisture out. Long term it will become an issue.

In my 35 plus years working for an automotive OEM (retired in 2008), I neither experienced nor heard of an OEM approving any specific after market product for their vehicles. This included the period from 2000 - 2008 to where my department had responsibility for (among other components) fuel injector systems, air/exhaust control valves, etc.. These particular components are not designed by the OEM's but rather by the major component suppliers (such as Bosch, Siemens, Continental, Delphi, etc.) under the concept of "black box designs". The OEM provides the performance requirements of the parts and specific mating parameters (e.g., injector o-ring to manifold material) but leave the component internals and expertise up to the supplier (e.g., internal injector o-ring design and material) allowing the supplier to develop their advantage over their competition (e.g., pricing and performance). The OEM and chosen supplier then jointly coordinate the verification program to prove out the design.

The OEM's and suppliers do not have manpower and capital to test every after-market additive. In addition, the after-market additive suppliers do not have the facilities/capability to endurance test every vehicle/application that they are selling to.

Back in that time frame I had a vehicle at the dealer for an unrelated issue. The write-up tech tried to push a BG program. Here's how the conversation went:

Is this stuff approved by the manufacturer?
Absolutely!
I have the corporate fuel injector specialist on my speed dial. Should I call him to confirm? (It was not an idle threat - he was on my speed dial...)
I guess you're not interested in the package...

There is a time and place for using injector cleaners but it should be one under the name of the name of the OEM. Back in the time above, it was a cleaner that was made by an after-market supplier but had been approved by the injector manufacturers we had sourced to.

How do you know which fuel is "top-tier"?

While I agree with the concept, it may be more complex than you think. I had experience with Fuels & Lubricants specialists back in 2007 and found that service station supplies are refinery-based more than brand name based. For example, a BP station may get BP gas one week and Exxon gas the next - they are only contracted to sell their instore products (oil, coolant, etc. ) from their parent company and not the gas...and Sam's Club/Costco get whatever the cheapest blend the refinery is selling that week (which may be that BP gas one week and "xxxx" brand the next...)

Those same specialists conducted quality audits every couple of years and the highest quality gas was - at the time - from a regional chain in the Midwest known for their competitive pricing. Based on the above, they stopped doing the audits.

This may have changed since 2007, but I doubt it.

I bought an 86 Toyota 4-Runner 4WD with a 2.2L RE engine. My daughter and her husband (now EX) had both graduated with a college degree in automotive mechanics. The SIL was working for a dealership for one of the major US manufacturers. Every 20 months or so, I would notice the 4-Runner would start idling roughly at a stop sign or stop light. The fix was to take it to the dealer and pay approximately $250 to have the injectors cleaned. After the 2nd time, I got fed up with the expenditure. I called the SIL inquired about the cost of the professional injector cleaner tools and asked his advice. He recommended I fill the tank with Chevron gas which had a Techron injector cleaner additive, buy a bottle of the Techron additive and add it to the tank. Then put the vehicle on the road until it need to be filled up again. Then stick with Chevron gas. I did as he instructed and never had to have injectors cleaned again in that 4-Runner or any of my company cars or other personal cars since then. At the time, Chevron was considered a top tier gas.

My only experience with injector cleaners was way back in the 80's. My '84 Buick Regal Ttype started running really funky after some bad gas came to town. I pulled the 6 injectors and took them to an injector shop. It was a Friday afternoon just before they closed. The guy put the 6 injectors in the machine and ran a test spray. The differential was 73%. He said that was BAD. One of the injectors would only 'pee', it wouldn't even spray. He then fired up the acetone, and the machine power washed the injectors the entire weekend. The guy didn't shut the machine down until I came in Monday at lunch time. He stopped the cleaning and ran another spray test. Differential was now 97%. The 'pee' injector was still lagging a bit. He told me that was 'within spec' but if I wanted to wait another day it might come up a bit. I just bought a new injector from him to replace it...

I just figured: If straight acetone spraying thru the injectors @ 90psi for 56 straight hours could barely clean the injectors 'to spec', then I was probably not going to expect some stuff added to the gas tank to help much...

Thanks for jarring my memory, Ken!

Chevron Techron was the cleaner that the injector suppliers recommended.

Bob,
I use this list to identify Top Tier fuel suppliers. There is usually a green "Top Tier" sticker on the pump as well. Do you think this is credible, based on your experience in the business Sir? LINK

You are correct that supplies are refinery-based...in most cases, gasoline isn't "branded" until it's in the tank at the station and you look at the sign. But my understanding is that the system is setup so that orders get the additive packages applied as part of the delivery process so that each "brand" gets gasoline that has the additive formula for the given brand, ranging from "minimal" to "it slices, it dices" for many top-tier brands. Top Tier supposedly encompasses brands that have additive packages that exceed some threshold. It's apparently a licensing situation for the name, however. The listing can be found at: https://www.toptiergas.com/licensed-brands/. Obviously, one has to mentally keep track if this is a shopping thing for them. I keep it easy...99% of the gas I buy comes from Costco because it's the best price in the area and we get another 4% back on the card rebate. They actually do promote that they are a Top Tier brand.

I've been told in the past by drivers I knew who were hauling fuel that there were trucks from all the well known chains lined up and being filled from the same fuel source as all the others. In their opinion everyone was receiving the same fuel whatever the additives were. Whether this is valid info I don't know. I've not ever had a fuel injector issue that I can recall. I do know bad gas can cause such things though. I think because of EPA standards etc there are fewer issues with contaminated fuel then there once was. Storage tanks being upgraded mainly.

It wouldn't surprise me...

Back in 1979 when I briefly worked for Mobil Oil after getting out of school (I ended up not really "fitting into" the strict corporate structure they had at the time) the company had their own refining, their own storage, their own pipeline, their own terminals and their own fleet with custom trailers designed to deliver product efficiently. Once all the mergers and acquisitions and subsequent divestitures of infrastructure hit the industry, that kind of thing became a "dodo bird", for the most part.

The 2007 incident I referred to earlier was stuck idle air control valves (not to be confused with stuck throttle!) on a vehicle/engine combination that had been in production for a few years without issue. Teardown of failed parts showed a foreign substance that had built up on the control valve seal. Chemical analysis of the substance determined that the only way it could be present is thru the combustion process. We knew that since day1 we were getting a slight bit of exhaust backflow thru the valve but couldn't understand why the issue just started happening.

We took a deeper dive into the warranty data and found there were zero cases west of the Mississippi or from the New England area. Breaking down the data further showed the cases concentrated on the I-65/75/77 "Snowbird" lanes from the Midwest down to Florida. Customer Relations phone calls to the affected owners revealed that they almost exclusively purchased their gas from wholesalers (i.e., Costco/Sam's Club/Meijers).

It was at that point that we brought the Fuels & Lubricants Specialists into the discussion and learned it was probably refinery dependent (due to an unknown additive) and not station dependent (i.e., don't blame the wholesalers).

In the audits I referred to earlier, the top gas consistently came from Speedway. Their parent company (Marathon) performed OK. At the current Top Tier website, Marathon is listed as Top Tier but Speedway is not.

Fuels and Lubricants are unusual commodities. I had experience once on pre-production wheel bearings where we had two production runs: one passed, one failed miserably. They came from the same bearing plant off the same line. One was made with Exxon grease made in Hamburg, Germany - the other was made from the same Exxon grease - to the same specifications - made in Pittsburgh but with a different "filler" source. The filler contained material that contributed to excessive wear.
