Facts n figures aside, I put in premium and it goes like stink.
I put in regular - still goes like stink but takes a bit longer to get there

 

Yeah, I was spewing today Ryan.

Was going to put regular @ 1.36. (Thought, naa, put premium - first time @ 1.43)

Drove gf home, and what do I see? Regular @ 1.24. I was SPEWING.

 

Well,compresion is set by the engine but if you have high temperature on the engine and a fast burning gas combustion will begin before its optimun point (max compression). Here in P.R. the temperatures run over 94degrees 90% of year .So I dont know you but my butt dyno knows when im using reg or premium . and my odometer marks 200 miles per tank on regular and 260 mpt on premiun so well, I dont know maybe my odom is a liar and need to be changed !

By the way im not a mechanic specialist ,just a musician and all of this was learned here on the net.

 

Sounds like the kinda guy Jeremy Clarkson would say would buy a diesel.

 

yea, it hessitated and backfired for a second then went back to normal after starting it up. Yea I know about the FQ's being hot, Im gonna acctually get the FQ mirrors and stuff to make it a Ralliart FQ plus a few things under the hood. but yea, thats just me with the FQ 162 thing.

 

same here

I noticed this on really hot days, but if the temp is at like 70 degrees out then my car feels fast.

 

So as mentioned previously I used Premium Octane 98 and I defnitely notice the responsiveness. I was driving for a while and all when good and all and all of a sudden a few 20-30kms later, gear 1 and 2 just felt much more responsive, I'm not sure but perhaps the ecu must've recognised the new gas and reacted positive to it.

?

 

The same happens here in P.R. but premium solves it! 92-94 degrees it really hot !In the nights 90 degrees its the rule most of the time.The problem its premium (93oct) its now 79 cents a liter vs 61 cents liter for regular (87oct).
