Review: Value for money - Castrol is an amazing brand for both 2 wheeler and 4 wheeler. I am using castrol products for last 12 years and they turned out to be superb. My scooty has no problems because of regular maintenance using castrol products and same goes for car. Infact, the best mechanic at my place use castrol products only. Not the cheap knock off.
