Last time I switched to Zic 4T oil 20w-50 (fully synthetic oil ) from GTX in my Raider 110 which is 10K driven so far, only for having experience. But so far I have not gained any good experience with the ZIC 4T oil and driven 1100 km ZIC Oil. The engine is not running smoothly moreover, producing more heat then before since its first start on ZIC.
Before ZIC, I was using Castrol GTX Oil in my Raider 110 and I think (after using ZIC) GTX is better then this ZIC 4T.
This result is almost against the experiences gained by other USERS of ZIC. I don't know why is it happened? Although I bought this ZIC from a good dealer of Oil and also changes my car oil from there. I think synthetic oil (like ZIC 4T which is JASO MA/API certified) is not good for bike like Raider. Suzuki Raider manual says that you should use 10w-40 API SF or SG grade OIL.
What other members say about mine experience?
Its means I should use the API SG / SF 10w40 oil, then what is best in this category?
