That -35504 made both of my Kias run much smoother with same Penn Platt oil.
One way to prolong this engine's life is to replace catalytic converter at or before about 100K miles. They disintegrate and ceramic filler dust gets back into cylinders forming abrasive paste. Then [censored] breaks loose.
What? Last I checked exhaust (cat) is a one-way street...
In theory it is but since they moved cat close to exhaust mani the powder finds its way back into cylinders. I bet you may have heard of back pressure too, occurs during engine start and stop. This is not my imagination but a fact, seen many engines failed and cats cut open after that.
Cylinder walls get scored and crankshaft bearings eaten and turned, rods broken...

Documents show that high exhaust gas temperatures can damage the catalytic converters, which control pollution. That can cause abnormal combustion and damage pistons and connecting rods. A failed connecting rod can pierce the engine block and cause oil leaks that can cause fires.
