MudisFun Posted January 11, 2005 Share Posted January 11, 2005 I love my 85 GL-1O and I want to show it. As far as the oil goes I used castrol syntec, but I hear amsoil might be best bet. As far as grade, I just don't know, 10w-40 seems to be the best idea but with 125K I wouldn't mind having it a bit thicker. It would be great to get some opinions. I always hear the genuine subaru oil filters are the best. Last time I put on a k&n. This next time I want to go all the way! When searching for the filters I found four: White - American?- crap $5 Blue - NPN- $5.97 Black - Bosch - $3.84 Gray - Denso - $8.66 By first look I would use a bosch, but does anyone have info on the npn or denso?

Mudboat Posted January 11, 2005 Share Posted January 11, 2005 I use Castrol High Milage (5w) oil in my EA-81. I've tried a synthetic once (Royal Purple), but I lost some compression and also started leaking oil once the deposits washed away. Shortly after switching back to 100% petroleum based oil, I had a piston burn and rings seize up. After the repairs were made, I strictly use the High Milage oil.... I like it....

PeterD Posted January 11, 2005 Share Posted January 11, 2005 Napa Gold or WIX oil filters are all i will use. and i just run 10w-30 dino oil in the winter. im not sure what full synthetic will do to a previously uncared for motor. http://www.scuderiaciriani.com/rx7/oil_filter_study/ Link to comment Share on other sites More sharing options...
torxxx Posted January 11, 2005 Share Posted January 11, 2005 If your engine leaks oil at all, dont use synthetic. you are just paying more to dump it on the ground. For a filter go with a purlator pureOne filter part #24457 best filter on the planet Link to comment Share on other sites More sharing options...

For a filter go with a purlator pureOne filterpart #24457 best filter on the planet good filter but has restrictive filter element. could be a good thing or bad i don't know...I use WIX becuase its a better built filter and is about 3 bucks cheaper than the PureOne at my local auto parts store. best filter wold have to be Mobil 1....from numerous things i have seen and heard about...but they are not cheap. Whatever you do stay away from FRAM or any company that has filters built by FRAM...if you ever get a chance to look at the internals you will know what im talking abou.

Snowman Posted January 12, 2005 Share Posted January 12, 2005 Go with a Subaru filter. They can be purchased for $60 per case of 12, which is comparable if not better than most high-quality filters. Link to comment Share on other sites More sharing options...
MudisFun Posted January 12, 2005 Author Share Posted January 12, 2005 But which one is the subaru filter? The blue, gray, white, or black bosch? Link to comment Share on other sites More sharing options...
Snowman Posted January 12, 2005 Share Posted January 12, 2005 But which one is the subaru filter? The blue, gray, white, or black bosch? I'm not sure I understand your question. I'm referring to the filters you can get at the Subaru dealer, that are white and say "Subaru" on the side in blue letters. Link to comment Share on other sites More sharing options...
