Review
Idemitsu is surprisingly not a well-known brand, since it has provided me with quality and remarkable products to further improve how my car performs. The Idemitsu Touring 15W40 JASO DH-1 was no exception, it had significantly improved the wear and tear rate of my engine parts, along with adjusting my engine's performance to match on how I drive, thus giving a better fuel efficiency. I've always been using fully synthetic engine oils, but this Touring 15W40 JASO DH-1 outperforms the rest of the fully synthetics. I'm loving this oil, and I doubt I would want to change to any other anytime soon!

What I like
Provides better engine performance to suit my driving style, along with giving a better fuel efficiency.

What I do not like
A little costly for a fully synthetic engine oil, but well, it performs great!
