An oil thread! Ahh. . . Opinions.
has nailed it here, again. For the most part, when speaking of "conventional" lubes, oil is oil with no regard for brand. Synthetics are a different story, and for every individual who claims to have had excellent success with one brand or type there will be another who will claim that it completely ruined their car and that they are still considering litigation.
So, my opinions, such as they are:
-I use the Amsoil XL 0W-20 in both of my cars (2017 Civic EX HB and 2013 Acura ILX 2.0L), and I have for a number of the cars preceding it. It's on the higher end of the pricing spectrum where I live and not very easy to find (one of the local farm supply stores carries it regularly, though), and I've been very happy with the performance.
-Mobil 1 is readily available pretty much everywhere (and usually on the lower end of the pricing spectrum) but I don't feel that it's the product it once was. I'd want to see some sort of verification that it isn't any longer 100% synthetic (it isn't labeled as a blend), but I have read elsewhere (non-forum and non-blog) that the overall performance of the Mobil product isn't what it used to be.
-I've used Redline and Motul in motorcycle applications only in the past and had satisfactory results, but having never used them in a car I don't know that I can endorse them.
-Royal Purple is a racing oil and should probably be used only in that world. Racers don't attempt to put their oil through numerous heat-and-cool cycles like a street vehicle, and the oil is generally changed out after just a few uses.
Again, this is ONLY my opinion, but I think you should find a product that you'll be able to get a steady supply of and use that one. I encourage a synthetic as they are inherently better at the task, especially in a turbocharged engine, even if you choose to go an extended period between services. Your other important consideration (and one which I rarely see discussed on forums like this) is the OIL FILTER you choose to use. Don't go cheap. . . Fram oil filters are crap
. WIX and Hastings make a good aftermarket filter, but I myself use a Genuine Honda filter every time. I don't know what brands are available outside of the US market, but I used to run MANN filters on my VW's back in my days of VW fanaticism.
Finally, I leave the standard disclaimer here: These are merely my opinions, and these opinions are based on my myriad of experience with 60+ automobiles and a handful of motorcycles, but also more than a million miles driven since 1983. Your results (and opinions) may differ, and I have only offered this here because someone asked.
