jakeireland Posted June 10, 2019 Share Posted June 10, 2019 I've done a search but can't find anything, so, what oil would people recommend?! Doing an oil and filter on my 2008 STI in the next week or so, as well as diff and gearbox oil just to be sure. I'm going to go for Millers gear oil but not sure on the engine as I've seen so many different recommendations! RCM say they use 15w50 but that seems a little extreme?! Help me out please!

jakeireland Posted June 10, 2019 Author Share Posted June 10, 2019 Thanks guys! Any recommendations of brand etc? Millers? Link to comment
johnmacdonald Posted June 10, 2019 Share Posted June 10, 2019 Millers 5w40 nt competition oil every time. Have used it for years - expensive but worth every penny! Similarly, Millers for the 'box and diffs... Link to comment
Oilman Posted June 11, 2019 Share Posted June 11, 2019 Hi, Is it standard or modified? Road or track use? Cheers Tim 1 Link to comment
conrod Posted June 11, 2019 Share Posted June 11, 2019 I've also used millers for years for engine,gearbox and diff Link to comment
Lockheed Posted June 11, 2019 Share Posted June 11, 2019 I don't want put anyone off using Millers or indeed start an argument but I did hear a few people complaining of additive drop out ,this was at least 2 yrs ago and I think they have changed their Nano line since. I now use Motul 300v only because my engine builder told me to. 1 Link to comment

Help me out please! i always use Fuch pro race fully synthetic 15w50 on tweaked Sti 2.5ltr and high tuned 2.0trs. As advised by some tuners. But PPP 2.0ltr WRX 2.5ltr ok on 15w40. I dare say 15w40 would be ok in above. I have used Motul. 6 years thrashing my Hawk T20 around tracks it never complained. i changed it either just before or just after a trackday, depending on milliage. So my average oil change was 1,200 miles. Now my T25 430bhp has an oil cooler and less temperature variation, my oil changes are more like 1,700-2,000 miles. My 2011 2.5 370bhp has forged pistons so be OK 15W40 but its run on Fuch 15W50 as easier to keep one oil Cost of oil, filter labour under￡70, so peanuts compared to a rebuild. So most people get given some advice and if works out, they stick to that plan, even if technically incorrect. Tony Oilman will give more wisdom than us plebs Link to comment
