Frequently Asked Questions

My engine is smoking heavily—is this related to the oil?

Excessive smoke can indeed result from an incorrect mix ratio or the use of an unsuitable oil. Modern TC-W3 oils like this one produce very little smoke thanks to their optimized formulation. First, check that the oil-to-fuel ratio complies with the manufacturer’s recommendations. If the problem persists despite using a compatible oil, an adjustment to the carburetor or an inspection of the fuel injection system may be necessary.
