Which is better fully synthetic or semi synthetic engine oil?

Semi-synthetic oil can achieve higher levels of performance than from mineral oil alone. Semi-synthetic oil is more wallet-friendly than fully synthetic oil as it comes at a reduced cost whilst still giving you some of the benefits of full synthetic oil.

Is fully synthetic oil better than semi?

Generally, semi-synthetic oils are more expensive than mineral oils and cheaper than fully synthetic oils. Semi-synthetic lubricants offer fewer performance enhancements, protect components less and degrade faster than synthetic oils. Semi-synthetic oils are purer, better-flowing and longer-lasting than mineral oils.

Is fully synthetic oil Better?
