Extending Your Engine’s Life: motul engine oil 10w40 Care Guide

Using premium oil like Motul 10W40 is a great start, but proper care and proactive maintenance ensure you get the most out of it and your engine for years to come.

Regular Checks and Top-Ups

The simplest yet most effective maintenance step is regularly checking your oil level. Make it a habit to check your oil at least once a month, or every few fuel stops.

  • How to Check: Ensure your car is on level ground and the engine has been off for at least 5-10 minutes (allowing oil to drain back to the pan). Pull out the dipstick, wipe it clean, reinsert it fully, then pull it out again to read the level. It should be between the “add” and “full” marks.
  • Top-Up with Care: If low, add Motul 10W40 slowly, a little at a time, rechecking the dipstick until the level is correct. Avoid overfilling, as this can cause its own set of problems.

These simple motul engine oil 10w40 tips can prevent serious engine damage from low oil levels.

Understanding Your Driving Conditions

Your driving habits significantly impact how quickly your engine oil degrades. Adjust your oil change intervals accordingly.

  • Severe Conditions: Frequent short trips (engine never fully warms up), heavy towing, prolonged idling, extreme temperatures, or dusty environments are considered “severe” driving conditions. Under these circumstances, you may need to change your oil more frequently than the standard recommendation.
  • Normal Conditions: Regular highway driving with minimal stop-and-go is considered “normal.” Even then, don’t exceed your manufacturer’s recommended interval.

Being honest about your driving conditions helps you maintain an optimal oil change schedule.

Filter Choices and Their Impact

The oil filter is just as important as the oil itself. A cheap, inefficient filter can negate the benefits of premium Motul engine oil 10W40.

  • Quality Matters: Invest in a high-quality oil filter that matches your vehicle’s specifications. Premium filters offer better filtration, higher capacity for contaminants, and more durable construction.
