zebedy Posted September 23, 2014 Share Posted September 23, 2014 Was on the phone to the previous owner of my car about a small issue and one thing let to another and the petrol question popped out in conversation. It turns out that over the 4 years he had owned my car, he only put cheap Lower Ron petrol in it. Ive only used the Higher Ron fuels since ownership. so my question is, can the fact that he used the cheapest unleaded, does or has it damaged anything inside the engine or fuel lines??? also Remembering years ago in my teens you were able to pour some sort of additive into the fuel tank to increase the Ron, but might be totally wrong here as im unsure what it was and what it did. - cheers Zeb Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 23, 2014 Share Posted September 23, 2014 Very possible it's caused plenty of damage, but sadly that's just a risk you'll have to take now. Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 23, 2014 Share Posted September 23, 2014 Assuming, of course, yours isn't a HR model. Quote Link to comment Share on other sites More sharing options...
hensh65 Posted September 23, 2014 Share Posted September 23, 2014 Been discussed a lot on here and when I saw your title I feared for your safety Someone will be sure to correct me if I am wrong but the damage is caused after the DE exceeds 5KRPM. So if he never really hooned it about then you might be ok although not great. Quote Link to comment Share on other sites More sharing options...
david85williams Posted September 23, 2014 Share Posted September 23, 2014 (edited) Can the fuel affect the DE and HR in different ways? I always thought it was bad for both.... Edited September 23, 2014 by david85williams Quote Link to comment Share on other sites More sharing options...
Ekona Posted September 23, 2014 Share Posted September 23, 2014 HR can knock detect better than the DE, so will retard quite happily. DE cannot at high RPM, which is where most of the damage is done. I cannot fathom people who put 95 in when every single time they open the filler cap it states 98 or higher!* *At least, I think it does. 1 Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted September 23, 2014 Share Posted September 23, 2014 It does state it on the filler cap And yes you could and still can buy octane booster Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted September 23, 2014 Share Posted September 23, 2014 The trouble with the DE ECU is that it doesn't monitor knock after 5K RPM, so if the fuel used was 95ron then IF the engine was reved/loaded heavily over that threshold it could have caused damage....however having said that, the weak point of the DE is the rods, and det can bend them, BUT normally before that happens you would have likely seen a drop in power duet to piston ring land and ring damage, so if you run a compression and leak-down test it will hopefully put your mind at rest.

brillomaster Posted September 23, 2014 Share Posted September 23, 2014 (edited) my DE is going to have to live with 97 im afraid, since that's what sainsburys super is (and I believe a few other supers are 97 RON as well) but even so, I only go above 5k once in a blue moon anyways.

Grundy Posted September 23, 2014 Share Posted September 23, 2014 At first I thought, oh god not ANOTHER petrol thread After reading, was relieved was a different kind, asking for advice and help.... And then yet we go back to 'what we put in our tanks, what we should use etc' Quote Link to comment Share on other sites More sharing options...

zebedy Posted September 24, 2014 Author Share Posted September 24, 2014 cheers guys. I know that Ive not taking it over 5000 rpm as the car only commutes 2 miles each way to work each day with the occassional week end banter but nothing silly. Also I must confess that I too use 97 ron most of the time as its the closest garage to me. Lets hope that nothings been effected. Gonna get a compression test done on pay day to see whats what. thanks again. Quote Link to comment Share on other sites More sharing options...
