My motor came from japan, where there are no detergent oils (at least no use). That makes sludge and shit in my engine, so I took it to my friends work, jiffylube the other day. After a year, my engine still got the oil dirty quickly, so I got an engine flush and injector/fuel line flush. after everything I finished with my oil change and headed back on the road. felt way more responsive and I hit the P in MPH on the 120mph spedometer. I would estimate between 140-150. I think it went a tad past that because I was just haulin ass down the freshly paved road. my mileage is way better too! Go get the lines and injectors cleaned at the most, because it helped soo much. My lines and system had 150,000 miles of use tho. If you use crappy gas from arco and the like, you will see a better improvment because the crappy gas clogs and plugs your system faster than detergent gasolines from shell or cheveron or the like.
Definitely need to get this done to my car. Poor thing lived in D.C. most of it's life, I'm sure the injectors/lines are clogged to hell.
i put injector cleaner in my celicas petrol tank probably about every 3000 k's it does makes a difference and i recomend doin it every now and then. on my corolla i do the same thing but i use carby cleaner instead
+1. I always add Gumout products to all my cars. I would highly recommend Gumout all in one x2. Walmart, Target, Autozone or pretty much any store sell it and its around 6 - 7 bucks.
