The use of dielectric grease on spark plugs is indeed a nuanced topic with valid arguments on both sides. Dielectric grease, by design, is a non-conductive silicone-based substance primarily used to prevent moisture and corrosion in electrical connectors. When applied correctly-typically on the inside of the spark plug boot-it helps create a moisture barrier that reduces corrosion and eases removal during maintenance. This protective layer can extend the life of spark plug boots and maintain cleaner connections, which many mechanics value.
However, it’s important to clarify that dielectric grease does not conduct electricity. Therefore, it should never be applied directly on the electrode or the contact points of the spark plug, as this could impede electrical conductivity and potentially cause misfires or poor ignition performance. The grease’s insulating properties could increase the resistance required for the spark to jump, defeating the spark plug’s fundamental purpose.
Engine type and operating conditions also matter. For instance, in older or vintage engines prone to moisture ingress, dielectric grease can be a practical defensive measure. In contrast, modern engines with tighter seals and advanced ignition systems might see reduced risks of corrosion, making grease application less critical.
From my experience and discussions within automotive forums, the consensus leans towards moderate and appropriate use-primarily a thin layer on the inside of the boot rather than on the spark plug electrode itself. It’s a simple step that can prevent environmental damage without compromising electrical performance. Ultimately, understanding the engine’s requirements and following manufacturer recommendations are crucial for making the best choice with dielectric grease on spark plugs.

When selecting fuel for your lawn mower, it’s essential to prioritize the manufacturer’s recommendations found in your mower’s owner’s manual. Most modern lawn mowers are designed to run efficiently on regular unleaded gasoline with an octane rating of 87. Using this standard fuel typically ensures optimal engine performance and longevity without the need for specialized formulations. Higher octane fuels do not necessarily improve performance unless your mower’s engine specifically requires them due to design and compression ratios.
Regarding ethanol-blended fuels, many gasoline brands now offer blends with up to 10% ethanol (E10). While E10 is generally accepted for many engines, it can attract moisture and cause corrosion or gumming inside fuel lines, carburetors, and tanks over time, especially if the mower is stored long-term. For older or small-engine mowers not designed to handle ethanol blends, it’s prudent to use ethanol-free fuel or fuel additives that stabilize gasoline and prevent component degradation.
Fuel quality is critical-avoid using old or stale gasoline, identifiable by a sour or varnish odor, darkening color, or separation of layers. Stale fuel reduces engine efficiency and can cause starting problems or engine damage. Always store fuel in approved, tightly sealed containers in a cool, dry place away from direct sunlight and use fuel stabilizers if storing for over 30 days.
Brands such as Briggs & Stratton and Sta-Bil have good reputations for producing fuel additives and some ethanol-free options suitable for small engines. Ultimately, adherence to manufacturer guidelines combined with proper fuel storage habits will ensure your mower performs reliably and lasts longer.
