Hi friends i have a lexus is200 that in a short time will hit 120,000km ive been using Mobil 1 0w-40 synthetic oil i change it every 10,000km. Now the question is that i see in the mobil 1 site that they sell a 10w-40 high mileage engine oil for cars with 75,000miles. Do i change to this oil or stick with the one i use? Thanks guys.
