Hi Everyone,

I'm going to start doing the oil changes on my '08 MDX and have some questions about the oil.

The owner's manual mentions using 5W-20, however I've read that 0W-20 is recommended for the newer Acuras, is essentially interchangeable with the other, and is superior overall. Walmart sells 5 quart bottles for $25 which isn't bad at all for good synthetic oil. I kinda want to use it but at the same time I really like using what the owner's manual says, since it's obviously designed for the 5W-20. Also I've got a Camry that takes the 0W-20 and it would be nice to just have a single oil type I can stock up on when it goes on sale!

Any thoughts on that? Also filter recommendations would be appreciated too. Thanks!

It's fine. Perhaps even smart. I might not do it during warranty just to avoid giving Acura a reason to deny a claim (highly unlikely anyway). In the case of Mobil 1, the specs between 0W-20 and 5W-20 are identical at operating temperature and the 0W flows better on cold starts. Win-win really.

No, As Acura/Honda already spec´d out 0W-20 to be used in any of the J37s.


0W-20 is not really needed on the 3.7L MDX unless you live in places were there is always less than 32°F..
But as normal year round daily drive oil Acura/Honda does not recommend it for the J37.

Thanks guys, so it sounds like it would do the job, but maybe isn't necessary. I may just stick with 5W-20. Any thoughts on synthetic or not? The owner's manual says you can but to keep the oil change intervals the same as with non-synthetic. In that case I may just do regular, as I hear that it doesn't have a whole lot of benefits with regular use of the car if the oil change intervals are the same.

Not sure why they would say to keep the intervals the same. With synthetic prices these days (deals online or places like Costco where you can pick up 6 quarts of Mobil 1 5w20 for $35 I don't know that there is any argument to stay with conventional.
