After reading this forum comments, everyone recommends Mazda Moly primarily as it's a darn good oil and good for the engine. But they are costly. I thought of something which I do or rather doing with my Rolla and couple of my friends' cars and it has never, ever failed me. Every time the performance has been impressive considering engine noise, oil analysis done (later) and longevity. That being said, I am seriously considering putting a good synthetic 0w-20 Mobil-1 and then add 8 once of this: https://www.amazon.com/dp/ (commissions earned)
Many knows, many don't but the product is really good and I can personally vouch for it for having used it for 189,000 miles. Recently, there was a head gasket leak and I replaced the gasket. The engine purrs like new still and the top part was completely clean.
It has the required Moly and much more of it adding to the usual 0w-20 oil. Cost wise: I believe it'll be quite cheaper.
