ZACHARYSBEADLE Posted May 28, 2016 Share Posted May 28, 2016 My Legacy GT uses 5w30 engine oil but I recently put in GC 0w30 and have a leak.. Could this be due to the oil being too thin? Link to comment Share on other sites More sharing options...
seanyb505 Posted May 28, 2016 Share Posted May 28, 2016 Where is it leaking from? How many miles are on the car? Link to comment Share on other sites More sharing options...
apexi Posted May 28, 2016 Share Posted May 28, 2016 Without going into too much detail and getting too technical, highly doubtful and just a coincidence in my opinion. Link to comment Share on other sites More sharing options...

Max Capacity Posted May 31, 2016 Share Posted May 31, 2016 Do not put 0w oil in these cars. you should at least use a 5w if not 10w this time of year in an old engine. lots of us run 5w-40 year round. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.
