So, I have been on this website for over a year now and I must say I have learned a ton and it has been a pleasure to learn from some of the oil greats on this forum. There are definitely people with vast amounts of knowledge and it is easy to spot them in various threads on here. I cringe at some of the comments I made when I first joined lol, but you live and learn and this is an awesome forum for doing so.
However, on to the actual point of this thread. I’m sure someone will come on here and bash me claiming I’m “starting another XYZ thread” but this question has been burning a lot in the back of my head for a few months now. We praise Euro oils for their high HTHS and approvals/specifications they carry, but are they necessary for 90% of us? My wife’s car is a Nissan Rogue, which I’d never think to run a Euro oil in. Me myself, I have a 2021 Mustang GT that I daily drive, but it sees no track time, only spirited street driving on occasion with 7k RPM shifts, hard downshifts, and some engine braking. Does this warrant the need for a Euro oil with a higher HTHS of >3.5? I know there are more to Euro oils stoutness other than HTHS such as deposit control, ability to stay in grade, oxidation resistance etc. The owners manual for my Mustang recommends 5W-30 which has an HTHS of around 2.9-3.2 in most API/ILSAC oils we have here in the states from what I’ve gathered here on this site and various PDS’s. But am I gaining anything using an xW-30/40 Euro oil over an API/ILSAC oil? API/ILSAC standards seemed to be talked down upon, which I know have began to lean towards fuel economy improvements which I could care less about. I didn’t buy a V8 mustang to save gas money. My OCI is every 3-5K religiously. Daily driven with 60/40 split highway to city driving.
