Frequently Asked Questions
Can I use 10W-30 instead of 10W-40?
While 10W-30 will work, 10W-40 is recommended for better high-temperature protection. Always follow manufacturer recommendations.
How do I check the oil level?
Use the dipstick. Remove it, wipe clean, reinsert fully, remove again and check level. Should be between "full" and "low" marks.
Can I extend oil changes with synthetic oil?
Synthetic oil lasts longer, but always follow manufacturer intervals. Severe conditions require more frequent changes regardless of oil type.
