Guest SupNA95 Posted November 2, 2009 Share Posted November 2, 2009 Hi i recently bought my new supra its a Supra NA 1995 J-spec. As i know in japan octane is higher so i am sure the ECU is programed to run higher octane. So i am wondering is it ok to put normal unleaded in the car or does it have to be superunleaded? will it damage the engine in the long term with normal 95 octane Quote Link to comment Share on other sites More sharing options...
Kirk Posted November 2, 2009 Share Posted November 2, 2009 you'll be fine on standard unleaded, no damage will come to the engine Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 2, 2009 Share Posted November 2, 2009 Like m_life said, standard unleaded is fine. Though I have always ran my cars and bikes on high octane, doesnt do any harm Quote Link to comment Share on other sites More sharing options...
dukenukem Posted November 2, 2009 Share Posted November 2, 2009 Isn't it more of a problem if it's turbocharged? I've always filled it with the higher octane fuel, but I'm a bit of a petrol snob when comes to the supe. Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted November 2, 2009 Share Posted November 2, 2009 Tesco do 99 RON Quote Link to comment Share on other sites More sharing options...
Kirk Posted November 2, 2009 Share Posted November 2, 2009 higher octane is recommended for turbocharged cars but NA's dont realy benefit from it unless there has been ALOT of work done to the engine Quote Link to comment Share on other sites More sharing options...
stevie_b Posted November 2, 2009 Share Posted November 2, 2009 I've run my unmodified NA on "normal" 95 RON petrol for years (I've never put high octane stuff in it), and it's been fine. Quote Link to comment Share on other sites More sharing options...
Abz Posted November 2, 2009 Share Posted November 2, 2009 Normal 95 RON is fine, Though I have been running mine with V-Power 99. I've filled up with 95 RON before and felt a difference between the two. I believe in Japan they use 100 RON for fuel. Quote Link to comment Share on other sites More sharing options...
Meko Posted November 2, 2009 Share Posted November 2, 2009 i use 95 RON as well in my N/A, i did fill up once with Super Unleaded (£75) and cried 350miles later when the tank was empty, so now i stick with standard unleaded. Quote Link to comment Share on other sites More sharing options...
Dave Posted November 2, 2009 Share Posted November 2, 2009 I've run my unmodified NA on "normal" 95 RON petrol for years (I've never put high octane stuff in it), and it's been fine. there no point in putting high octane if you dont have turbos btw ive never used high octane in 6 six years and mine purrs like a cat Quote Link to comment Share on other sites More sharing options...

Meko Posted November 2, 2009 Share Posted November 2, 2009 350 miles!!!! Wow!! (don't get a TT will you ) if it was a TT i could handle lower miles, but the BM was in the garage so the 350 miles lasted me less than a week just to get to work and back.
