CombatCQB Posted July 15, 2014 Share Posted July 15, 2014 Just read this newsletter from Blackstone Labs which does oil analysis. I've done it since my 05 LGT was new. The article is about the lack of difference in oil brands, but the interesting point is that they had the most data for the EJ25 engine. So it seems that more Subie owners do oil analysis than other brand owners. Thought I'd pass it along: http://www.blackstone-labs.com/Newsletters/Gas-Diesel/July-1-2014.php Link to comment Share on other sites More sharing options...
GTPpilot Posted July 15, 2014 Share Posted July 15, 2014 I had never even heard of Blackstone til I started hanging on this forum. Now I send at least 1 sample a year for all the family vehicles. Informative and sometimes entertaining ! Link to comment Share on other sites More sharing options...
Brady Posted July 16, 2014 Share Posted July 16, 2014 I don't see where the article says that the EJ25 has the most data at Blackstone ... just that they had "more" data than for the Supercharged Mini. But it also wouldn't surprise me since the EJ25 has been in wide use with Subaru for a long time and variants probably account for 80-90% of vehicles sold in the last 15+ years with Subaru. I know the likes of Honda and Toyota sell many more vehicles, but I wonder if they have used variants of the same engine for so long. Link to comment Share on other sites More sharing options...

That's how I read it too. Link to comment Share on other sites More sharing options...
