An oil/filter change for a car costs 20-40$ in the US and costs 70$ ( 4000Rs ) in India !!! Cost of oil is 20$ it seems ( in the US it is 5$ max )....big opportunity for low end car service player enterpreneurs...if you have a service shop and a mobile app to notify for services and coupons, I feel there will be takers in the middle class car buyers in the country. I dont know anything about this industry, TOL...buy oil in bulk, get a couple of freelancer mechanics ( hire permanently later ) and one could make decent profit...
