Dave Llama Posted March 10, 2022 Share Posted March 10, 2022 Hi have been running 86 2.5 wrx on Shell v power but costing a fortune. Could I use a 98 rated fuel instead or as a mix and not affect engine ? Sorry first Subaru since nearly 90s so bit of a novice Quote Link to comment Share on other sites More sharing options...
Tidgy Posted March 10, 2022 Share Posted March 10, 2022 some people say yes, some say no, for me i'd only run it on 99 even if it costs £10 a tank more, cheaper than an engine rebuild. Quote Link to comment Share on other sites More sharing options...
