1 Lucky Texan Posted January 6, 2012 Share Posted January 6, 2012 Pretty sure the black Roki filters have been replaced. jamie at https://www.subarugenuineparts.com/index.php (she's great with question, races too! http://www.subiegal.com/ ) will know. she has helped me several times with parts and odd questions about parts.

johnceggleston Posted January 6, 2012 Share Posted January 6, 2012 the owner's manual also says that thinner oil, 5w30, will give you better fuel economy, but you must protect the car with the right oil for the right temps. Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted January 6, 2012 Share Posted January 6, 2012 Dave - same car, though we do less daily driving. Given that most of our trips are short ones, and Subaru recommends more frequent oil changes every 3,750 miles instead of every 7,500 if you do many short drives, your 5K guideline is about what we follow. Do you use any particular type of oil filter, or just any generic that fits? Factory only- the Subaru black filter that says "H6" on the box. I hear they are out of production, but as long as the dealer has 'em I'm using 'em. They are not that much- 9 bucks? Dave Quote Link to comment Share on other sites More sharing options...
mountainwalker Posted January 6, 2012 Author Share Posted January 6, 2012 Yep, $9.49 at a good local dealer, and they say they have a bunch Quote Link to comment Share on other sites More sharing options...
mountainwalker Posted January 7, 2012 Author Share Posted January 7, 2012 Said they were still being produced for the H6 engines. Not sure if true, just sharing what he said. Quote Link to comment Share on other sites More sharing options...
mountainwalker Posted January 7, 2012 Author Share Posted January 7, 2012 Before I found out that the best local Subaru dealer parts department had the black OEM H6 filters, I picked up a Purolator PureOne. Would you use the Black OEM H6 filters first? I'll be running Mobile 1 0W30 synthetic and changing oil every 5,000K. Quote Link to comment Share on other sites More sharing options...
the3rsss Posted January 10, 2012 Share Posted January 10, 2012 Good choice of oil and filter. If you want, I did this, send a sample to backbone labs and have your oil analyzed at your next change. It will give you good insight into how your engine is wearing and how well your oil is holding up. It's cheap piece of mind. 25.00 and your results are back in a week.

1 Lucky Texan Posted January 10, 2012 Share Posted January 10, 2012 If I was FORCED to dream up an excuse to choose one of those filters over the other, the thinking would go like this; suppose the previous owner ran 'dino oil' (conventional) and you say you will run synthetic; synthetic is very good at keeping 'varnish' in solution. That's why it always look darker/dirtier. So, your first fill with synthetic 'may' be cleaning out xtra varnish left by the previous oil. Could that increase the likelihood of the filter's media being clogged more than normal? If so, then the filter with the lower bypass valve opening pressure 'might' be preferred and I suppose that would be the OEM filter. but I doubt there's a practical difference - and you could probably return the PureOne for store credit if you never plan to use it.
