Bro, I would still suggest to continue using it. Just replace engine oil along with genuine oil filter, and pour the engine oil as per quantity mentioned in your cars owners / users manual. Check the level on dipstick, and keep on checking the level after a week or 2 on regular basis. And use the oil + filter up to 5,000 Kms.
If there is any drop in oil level, or it touches min. mark, please let the community know here. They will then guide you accordingly.
