Using fuel injector cleaner at every oil change hey guys, so i've been using Sea Foam fuel injector / engine cleaner (poured into the motor with engine oil) with the last two oil changes (roughly 4 month intervals). is this a bad thing? I've heard good / bad. Good: the usual, keeps engine / fuel injectors clean etc. etc. Bad: "carves" pistons due to the "cleaning" agent , frequent use of injector cleaner is bad Any help would be nice. I only use 1 can 50/50 split between fuel / engine. |
Depends on what car... But every 4months :suspicious: |
08 mazda that has about 60k on it now. my oil changes are every 7k or 4 mos' whatever is first... |
Ummm...what? Hope not serious. |
Am I reading this right? You're putting fuel injector cleaner in your motor oil? I've never used fuel injector cleaner in my life and never had an issue. Posted via RS Mobile |
yea usually fuel injector cleaner goes in your gas tank, not in the crankcase |
:lol fouled plugs galore if every 4 months in gas if in oil... your engine still runs? |
Honestly, has no one heard of seafoam? Yes in you can put it in your oil. Sometime I wonder if this is still a car forum. Posted via RS Mobile |

first off if you use injector cleaner too often it will likely start eating away at things like your injector o rings and more Second I hope your not serious about putting all this in the crank case. You should put Seafoam In through the throttle body not recommended for Inside the motor. If you do for some reason run seafoam in the motor oil, it should be a small amount and the oil would need to be changed within 20 kms If your worried about the oil system gunking up instead of risking damaging things with Seafoam in it run diesel oil instead for a oil change or two as it has lots of detergents in it which helps clean out the motor safely Your car is so new none of this is even nessecary anyways your just going to reduce the engine life by doing all this so frequently ...

Armchair mechanics are great people. 'I've never really used this but here's how you're doing it wrong'. OP: Adding seafoam to your oil keeps deposits from building up in the oil system, but they should take YEARS to build up, not months. I personally don't believe in oil flushes, but if you are going to do them, do it once a year tops. Every time you use one you cause a tiny bit of damage to all the bearing surfaces and cylinder walls. Not a huge deal by itself, but it's aggregate. I use a can of seafoam about every 6 months in my gas tank, probably way more than I actually need to. |
a can of seafoam is recommended to be split into 3 parts, 1/3 into the fuel to clean the fuel system, 1/3 into the valvetrain via a vacuum source, and the last 1/3 poured into ur engine oil. This way it'll clean out ur fuel system, ur valves, and what ever sludge is built/deposited in ur crankcase. That is the procedure written on the can is the recommended way of seafoaming ur car by many people. OP, u shouldnt be seafoaming ur car so often, BUT!! REMEMBER to change ur engine oil asap after using seafoam as seafoam breaks down engine oil i believe |
this is what I use: Sea FoamŪ SF16 - Fuel Additive | O'Reilly Auto Parts (it says fuel system but on the can it says fuel / engine etc..) and yes - I put 1/2 into the crank case while putting in engine oil and I put the other 1/2 into a full tank of gas as i'm pumping gas (gas , bit of sea foam , gas , bit of sea foam etc..) I will stop adding them for the rest of the year since last oil change was in Nov 12 , and I recently did one in March 13. For engine oil - I use synthetic (probably too much ) but the price difference is so nominal (+ $3/4 ). |

OP really need to ask himself what is he trying to achieve? What are the metrics he can use to measure? (oil analysis etc). Throwing in chemicals is not bad by itself, but whether it makes quantitative difference (not to mention cost benefit ratio), is another story. |

It's the same with using ATF as a flush. The way you're going on about it is borderline OCD. |
I personally don't believe in engine oil flushes on cars I own. Maybe when I first buy them if the oil looks like crap when I change it, but oil is a cleaning agent. Plain old oil, never mind all the other stuff they add in. As long as you keep up on regular oil changes, you shouldn't be getting buildups. Nothing wrong with running synthetic. I put Synthetic in my 79 Trans Am and my 83 Brat on the original motors, just to prove that it wouldn't hurt anything. It didn't. |
Modern oils, specifically synthetics have a lot of chemicals/detergents in them that prevent oil sludge or any kind of oil build up, especially with newer cars. It's absolutely retarded to seafoam a car more than once every 30,000 kms, and that's depending on vehicle, oil changes and driving habits. ie, an older vehicle with regular oil being driven in short stop and go trips will need a good seafoam treatment way more than a newer model car with synthetic oil.... There is a good chance you're doing more harm than good buy dumping that stuff into your system so often. |

When I get home ill link you to something that I know maxima users do to achieve better mpg. Kinda the same thing u do but with a diff additive I believe Posted via RS Mobile |
Oh the joys of seafoam... |
You would probably find more efficiency by get a OBD data logger with throttle position, fuel use and GPS interface to see if you can improve on your driving, or route especially if it is a DD than Seafoaming an already clean car. You should have a baseline state of the fluid sample of your car before you seafoam. Places like Blackstone often interpret the data for you, based on the year and mileage of your car etc. Quote:

SpuGen has the instructions right from what I remember, you're not supposed to be adding it every oil change and leaving it in there for that long. Quote:

.........but why? |

If fuel cleaner didn't work my next step was to check the spark plugs -> plug wires -> and last O2 sensor. Car wasn't abused - it was pretty much brand new when I got it. What happens if I leave it there until July? (Mar +4 months) |
