Fuel Consumption is high..Solved
Hi everyone I have 2015 TE, with 150,000 miles on it. I put magnusson SC on it 6 months ago circa 130K miles on the clock. Tires are yoko's geolanders 285/70-17. I also have a mild lift 2.25 on the front and 1.5 in the back. Otherwise, car is stock with no added wait such as steel bumpers. I had lift and tires since day 1 with 11k miles on the truck. Consumption increased a bit but not that much I would say I was consuming 11 to 13 L/100Km with mixed city and highway.
After installing the charger fuel consumption was normal, I could easily get 500Km on a fill up with 1/4 left in the tank. Recently I noticed that I cant reach 400Km per tank, and Have to fill up every other day. Computer is showing 17.5L/100km I think its around 20L/100km which is crazy high. No further mods on the vehicle so nothing changed. I have no lights on the dash and truck is running fine, no issues at all except for the fuel consumption. Reached out to magnusson who confirmed that I have the latest tune and to go back to stock wheels and tires. I'm looking for advise here as to what could causing such a high consumption blocked cats? Spark plugs? Air filter, MAF? I know the tires are heavy but its the same before and after the SC. Any advice would be appreciated. Thanks. |

Reset the dash indicator for MPG to see what you are averaging. Search forums on before and after MPG for using a SC. Heavy foot on the pedal to play with the SC ? |
It's also winter now. MPG drops as the air density is increased, requiring more fuel. I see the same thing with my own truck without SC and with my turbo vehicles. Hard to escape it.

Most fuel consumption issues are driver related--when my wife complains about her fuel consumption, it's usually waiting to pick up kids at school with the AC running; when she's actually driving she gets good mileage. |
I have 135k on my 4Runner, the last 45k with the Magnuson on it. Running 285/70/17 LT tires on it and get around 16-19mpg. In the winter I usually see around 15mpg. Like others have said, check air filter, spark plugs, general maintenance items. Odd to see a change like that without something else changing along with it.

Looks as though OP is in Dubai? Can’t imagine Winter fuel mix is an issue there. Sent from my iPhone using Tapatalk |
Check all 4 wheels, the inside parts too, if there's excessive brake dust you might have a dragging caliper. I did at about 140,000 miles.

New spark plugs just delivered, I’ll replace the plugs along with new air filter and report back.
If catalytic converters have carbon built up it should give a check engine light right? |

No change to driving style, spirited driving mostly. |
Please check of these :
Poor engine oil Poor quality fuels High usage of air conditioning Worn out tyres(low psi tire pressure) Wrong gears in wrong ways. |
