Synthetic VS. Regular oil reliability - Toyota Yaris Forums

RUFFSTUFF · 01-01-2010, 10:35 AM

If you change your oil regularly as scheduled, the oil as specified in your owner's/service manual will be just fine. To make a blanket statement that synthetic oil is better is inaccurate. Detailed analysis of auto oils has shown that each brand and each blend has its own characteristics and performance profile, with some "dino" oils outperforming their synthetic counterparts. Generally though, I believe synthetic oils may have better long term performance. If you wanted to change your oil every 7500-10000 miles vice 5000 then I would recommend a quality synthetic oil. I think your driving habits should one of the main determining factors.
