djspawn00 Posted October 30, 2006 Share Posted October 30, 2006 I went to get an oil change today at a nearby Monro service station. I requested 5w-30, but instead got 5w-20. Is there a big difference? The manager insisted that it would not have an adverse affect. I was running late and did not have any time to argue. Should I do anything or is the 5w-20 ok for my 02 gs300 with 48k miles. I appreciate all the feedback, thanks in advance. Quote Link to comment Share on other sites More sharing options...
