Review on HAVOLINE High Mileage Synthetic Blend 5W20 Motor Oil For Improved Engine Performance - 1 Quart, 1 Pack (223680720) by Lild Zimmerly

Old cars love oil. I have some old e30 BMWs and they are thirsty drinkers. revain had this at an excellent price so I bought 2 cases. Quick delivery. I've heard the saying if you switch to synthetic from regular oil you can't switch back, well, that only applies to Full Synthetic. My cars take conventional oil and this oil is a synthetic blend so after talking to a Chevron rep (very good customer service btw) they reassured me that it is an indusrty term and that all conventional oils are considered synthetic blends because of the additives they all have. I am happy about the purchase.
