Full synthetic provides the highest heat stability and oxidation resistance, synthetic blend offers mid-tier protection, and conventional delivers basic protection if allowed by the OEM.

• Full synthetic: best film strength for heat, towing, and long service
• Blend: budget-friendly step-up from conventional
• Conventional: use only if permitted by the owner’s manual

• New crush washer (where applicable) and proper torque
• Responsible oil/filter disposal included
