🔧
Reports of excessive oil consumption in high-mileage vehicles after switching to this product.
prob_01
Common root cause: High-mileage vehicles may have larger gaps in piston rings and seals. The detergency of the new oil might clean deposits that were previously sealing these gaps, revealing the natural consumption of a worn engine.
Step-by-step solution: 1. Check the oil level with a cold engine on a level surface. 2. Look for any visible external leaks on the engine or packaging.
💡 Pro tip: Monitor the oil level regularly (every 300 miles) after the change. Consumption within the expected range for the vehicle's age and condition is not a product defect.

⚙️ Hardware Setup, Adjustments & FAQs

❓ What is the difference between semi-synthetic and synthetic oil? cfg_01
Semi-synthetic oils (like this Castrol GTX Ultraclean 10W40) are a blend of mineral and synthetic base oils, offering good protection. 100% synthetic oils generally provide greater resistance to extreme temperatures and longer drain intervals.
