Fuel additives and EGR cleaning/kits, what does Oppo think?
I’ve noticed I’ve lost a few MPGs a fill up recently. Granted this could be a number of factors such as driving style, location (recently moved), different pumps (fills the tank up to a different level throwing off the calculations.) etc
I’ve covered the basic mechanical stuff. The air filter’s alright. I checked the spark plugs a few months ago (I’ll check them again anyway) and they were fine. I guess I’ll go ahead and replace the fuel filter. Although I’m sure that’s not the problem, longer reasoning than is appropriate in this post.
Also what does oppo think of EGR valve cleaners/cleaning? I haven’t gotten any codes, but it’s OBD 1. I had an audible vacuum leak one time that didn’t throw a code. Seen some kits for anything about those specifically?
Anyway thanks!

It wont hurt to try a egr clean, but in terms of carbon on the intake tract, combustion chamber or anything internally...no. not if you are running good gas through it regularly.

Although define good gas. Like anything sold in the first world or the fancy stuff with additives? Because I just run the regular 87 octane.

Costco? Or grocery store quality? Anything real gas station brand (87 is fine) should be considered good gas

If your ride has some miles on it, it wouldn’t hurt to pull the EGR out and give it a good scrub. No “kit”, just brake cleaner, some brushes, and elbow grease.

Well my dad has been using seafoam forever in all kinds of things. I put it in my diesel Mercedes sometimes, hopefully helps keep my injectors cleaner.

Before using sea foam, just go spike your gas tank with E85. Every now and then I’ll go add 4-5 gallons of E85 to my 15 gallon tank to keep my fuel system clean. Works great.

I’ve never really made it to that point, I’ve never used seafoam because it’s probably the last thing I’d ever try.
Can you check fuel trim numbers on your vehicle? Even without a check engine light, I’ve seen slightly dirty injectors cause fuel trim corrections that alter my fuel economy, most times even just a bottle of fuel system cleaner in the tank is all it takes to get the fuel trim back to normal. I’ve had some family drop in to have me check their codes, if it’s a fuel trim code, I usually just tell them to buy a bottle of Lucas fuel system cleaner and it often is enough to stop the light coming back on and correct the fuelling. Dirty MAF sensors can be a common thing too, Mine looked perfect last time it got dirty from installing a new K&N filter (slight oil residue) and a cleaning put my fuel values back to normal too.
Also just saying it because it’s worth mentioning, colder temperatures in winter will kill off a few mpgs, but you probably already know that.

has the weather also gotten colder since you checked last? Also, winter gas.

...unless you have direct injection, then quality gas doesnt matter. My friends ‘12 traverse needed a few cans of sea foam to take care of the build up.

I’ve used seafoam on the intake of many vehicles. Always had decent results. Obviously, the worse the build up, the better the gains. A lot of people here are posting about “quality fuel”, but if it’s got a carb, a lot of miles, or direct injection, there’s going to be some build up.

Yeah, DI is another matter entirely.

It’s port injection.

I’m in Texas so it’s not cold, barely cool lol. Idk if I can check the fuel trim. At least without it already throwing a CEL since it’s OBD1.
Honda OBD1 to be exact.

It’s been warmer (Moved from WA to TX.) I doubt they even switch to winter gas here since it’s still in the 70s most of the time lol. I’m not even sure they use winter gas in WA since it barely gets below freezing there.

So you just spray it into the intake? Kind of like some people do with water?

Find an easily disconnected vacuum line as close as possible to the throttle body or carb (so as to clean as much of the intake as possible)
Disconnect it while the motor is running (might have to put your thumb over it to keep it running) and then put that vacuum line into the bottle of sea foam. Let it suck it up as fast as possible and try and make it stall. Once stalled, walk away for 20 minutes to let it soak. Start it up, do it again and keep letting it suck until its gone. (washing it all down)
If it removes a lot of stuff, expect smoke. lots of smoke. Just drive normal and it will go away as it burns off.

I use it on my bike. A couple of times during the year, and for storage. It works as far as I can tell.

Ok, good, eliminates that as a factor. I’m not that familiar with the obd1 stuff other than reading and clearing codes. If you can get access to the long term fuel trim for bank 1 sensor 1 on that system, that might be a decent start. On an obd2 vehicle, it would be good to see zero, +/- 8, if it’s reading something closer to +20 it means it’s generally compensating by adding more fuel. If one injector is making the average fuel ratio lean, the system tries to fuel harder to adjust, and you use more.
