Hi there, new to the forum. I've been reading through lots of posts to try and absorb as much info as possible. So far I'm finding it hard to come to a conclusion on my car. I've got a '96 acura TL, the recommendation for this car is a 5W-30 oil, lately I've been using a high mileage for the oil changes and now I'm second guessing myself finding that I'm actually pouring in a thicker oil. The car has 110K miles on it, the car doesn't have any leaks so I'd like to go with the best performance oil that doesn't pose any risks to future oil leakage. I'm thinking I'll switch back to a regular 5w-30 next oil change but after reading on this board I'm curious about auto-rx, and synthetic oils. If anyone has experience with these honda engines I'd appreciate your input.
