I know there’s plenty of talk here and everywhere else about oil, and I’ve searched through nearly every one of them. I’ve decided to ask a bit of a noobish questions and request the opinions of you seasoned Honda owners out there.
Ever since my first oil change I’ve noted that the Honda guys only seem to fill the oil to just above the minimum mark on the dipstick. This has always concerned me a little as when it comes to the next service the oil levels usually dropped to the minimum mark. I personally would’ve thought it’d be better to fill the engine to the full mark. That’s a matter I intend to bring up with them when I take it in for its 20000km service this week. I’m also going to request they change the manual transmission fluid. At this stage I’ll let them use the Honda fluid.
Honda FEO here in Australia is a 10W-30 oil and made by Caltex.
And I now wish to upgrade to full synthetic Motul 8100. I drive 170km a day 5 days a week, most of which I drive hard trying to get the engine up into the VTEC range at least once a day (damn speed limits prohibiting VTEC in 2nd gear

) Usually the 85km trip to work is a fairly clean run with little stop start traffic, however half of the trip home is always stop start.
My main question is which would be the best grade oil in your educated opinions…0W-30, 0W-40, 5W-30, 5W-40. I’m in Queensland (Brisbane) where the temperatures never really drop below 5C (41F), and are very often above 30-35C (86-95F) with high humidity. I’d like to keep to the standard servicing schedule of 10,000km but I’m willing to change the oil myself at every 5,000km and let Honda do it every 10K.
Thanks for your thoughts opinions or recommendations of other oils J
Better get back to work, been here for 3.5hrs, and have yet to do a minute of it! Monday’s……m’eh L
