After much searching (on this site and others), I have not been able to find a definitive explanation and so I hope to elicit the professional knowledge of our oil experts here. I know there are opinions on brands, additives, etc and I am by no means an oil expert. I am an automotive repair shop however and very conscientious of what I offer my customers (type and specs). My rule has always been that I do not sell what I will not use in my own vehicles.
The story - I previously carried Kendall GT-1 Blend with Titanium in 5w-30 and 5w-20; and I use M1 for the 5w-30 DEXOS, 0W-20 Honda/Toyota and 0W-40 for the VW 502.00 spec cars. No issues but buying M1 in the quantities I use is cumbersome; and carrying 0W-20 and 5W-20 seems redundant.
Recently in an effort to give my customers the best oil (pricing is not a factor) and reduce the number of oils I carry, I decided to switch to Kendall GT-1 Full Synthetic with liquid titanium. I purchased a drum of 5W-30 and 0W-20 which covers 90% - I still have some odd applications where I need specific oil but again those two drums if I did my research correct, will cover 90% of what I do.
The two issues I came up with (and no one including my salesman can sufficiently answer) - am I doing a disservice by putting the GT-1 Full Synthetic 0W-20 with Titanium in every vehicle calling for 5W-20 - thereby covering both grades with one product. Common applications of course being Honda, Toyota, '15 and newer GM for the 0W and Ford/Chrysler still pushing 5W on several applications.
And what seems to be more of an issue - I had the choice between GT-1 full synthetic DEXOS or GT-1 full-synthetic with Liquid Titanium but not DEXOS. When asked, it was basically explained that the Titanium version is as good or better than the DEXOS, the only difference is that GM will not license an oil with additives they have not approved (Titanium). I researched and found Castrol with Titanium is Dexos licensed so that argument is out and when I mentioned that, I had no response. I am not anti-GM (previous employee in fact) but I find it difficult to think that oil not labeled DEXOS is not as good (obviously defined in several different ways). So in short, can I put the non-Dexos Titanium ladened oil in or should I get DEXOS even though more than half of my customers are not GM vehicles. I def am not carrying a drum of 5W-30 DEXOS and 5W-30 Titanium so which is better for all of my vehicles?? (GM dealer warranty push back is not a factor either).
Many thanks in advance for your anticipated responses and time.
