Catalytic Question>>>

Got a 2010 SR5 back in November...strong catalytic converter smell at times...is this normal for break in, or should I get it checked? Noticed it on short in town trips, approx. 3-5 miles...thanks...

 

I've never noticed a smell on mine.

 

sometimes the additives in gas make them smell.

 

i picked up in december and ive smelled the same thing a few times.

 

Thanks...will keep a nose on it. Have been using PURE fuel, no ethanol YET in their fuel...

 

Short trips are not sufficient to bring the cats to proper operating temperature. Partial load (engine), engine to operating temperature, vary load/throttle input while breaking in. This will eliminate the platinum palladium "rotten egg" odor.

 

Thanks much 812, one less thing to worry about!
