I have a Swift 2015 but I'm not sure whether if I should go for Suzuki's own engine oil or should I go for Zic?
If you want warranty, better stick to SGP until the warranty is over. using other brand under warranty period will void it.
Why do you want to change is there any problem? SGP is a good oil made only for suzuki vehicles.
SGP is re-branded Total oil...you can use it in any car....
Suzuki claims that SGP is designed for suzuki cars.
Beware of fake oils. From Suzuki dealership and company pumps you will get genuine oil, from shop likely to get fake oil.
you must go for Zic A+ it gives best in terms of mileage, engine safety etc.
I have Swift 2015 and I am using ZIC XQ. ZIC is definitely the best oil available in market.
Please suggest semi/fully synthetic good engine oil for swift 10,000 KM drive.previously I am using SGO Ultimate 10W40.
as per user manual it should be 10W40 SM or SN .
Finally I decided to give a surprise to my Suzuki Swift ODO 9,000 Kms.
Liqui Moiy High Performance Gear Oil (GL4+) SAE 75W-90
Liqui Moly Synthoil High Tech 5W-40 Engine Oil.https://www.liqui-moly.eu/liquimoly/produktdb.nsf/id/en_1306.html?OpenDocument&land=GB&voilalang=e&voiladb=web.nsf
Engine oil can run upto 10,000 KM easily as per the engine oil manufacturer.
My swift ODO is around 9,000 Kms and i will change Engine and gear oil on 10K ODO. Previously I was using SGO Ultimate and SGO Gear Oil.
Bye bye to SGO and Suzuki Warranty
