Hi,

When I went to my usual mechanics this pass weekend to change
oil, he asked me to start filling 10-30 oil from now on. (was 5-30 before)
He said it makes no difference since my car is old and has
significant mileage on it. Is he right? So should I start to fill with 10-30
oil from now on?

My 98 Accord has 83K miles on it, and I live in Sunny California.


Thanks,
EH
