not exectly, honda buys oil from both caltex and total in batches to keep a competition between suppliers, i always asked them to get me the caltex one which is the same caltex formula 10w30, unfortunately now honda has stopped the mineral oil and only there 5w30 Fully synthetic oil is available with them,,, i haven't yet decided to either stick to my current havoline formula 10W30 (buy it from caltex pump since not available with honda) or move on to 5W30 fully synthetic, i have 2 honda city current model one is around 50k driven other is @ 94 k,
