skybren Posted August 3, 2005 Share Posted August 3, 2005 I recently bought an Impreza sport wagon and it pings like my old Loyale used to. I know I will check the other gas staions out on regular. By the way it is not turbo. Do I go to the medium gas or the high octane? Any suggestions and thanks Quote Link to comment Share on other sites More sharing options...
Andyjo Posted August 3, 2005 Share Posted August 3, 2005 throw in 87, it'll love it, the pinging is normal... mine's done it since the day i bought it, and nothing has ever come of it.... Quote Link to comment Share on other sites More sharing options...
friendly_jacek Posted August 3, 2005 Share Posted August 3, 2005 I could be wrong but i thought some MYs (mid 90's) required 89 gas. Quote Link to comment Share on other sites More sharing options...
99obw Posted August 3, 2005 Share Posted August 3, 2005 Pinging is hard on rod bearings among other things. Pinging should be the exception rather than the rule. Run what the owner's manual says and do CC cleanings to reduce pinging as needed. Quote Link to comment Share on other sites More sharing options...
