How many more miles per gallon have you been getting.Premium, more money but more miles per gallon and clean engine giving best performance
Good to know, maybe that's also a way to help prevent an engine from excessive oil consumption down the road.Don t know how much more, since i always filles up with premium 91 or more when available, I have done this to all my previous cars (67) and never had cylinder head problems or any fuel related parts
Octane levels are only relevant with compression level on engines. The compression ratio is around 10.0:1 for the NX, which is relatively low. You will run perfectly fine on mid or low octane. High octane would be pointless. It's more a mind game and waste of money.How many more miles per gallon have you been getting.
I was reading on somewhere a while ago that using a higher octane than recommend doesn't result in any benefits, performance or gas mileage.
Yup!Using the premium is just choosing to spend more for no good reason. Only certain engines need premium fuel, and the manual will tell you. I just implore you to do some research on this so that you don't waste money on premium for no benefit.
Well said and I agree completely. Would not even consider putting cheap gas in a Lexus. Always used premium in my vehicles, ski boat included. They just run better!!I used to believe that there is no significant difference between regular and premium, so why spend unnecessarily. Then I got very dissatisfied with my 'BMW' because all through the nine years I drove three models, i used regular fuell. Then, one day i decided to go premium. The difference was obvious. The car was more responsive more "willing" to give me an enjoyable ride, whereas before, it was like an unwilling, lethargic beast of burden dragging it's four feet. Needless to say, i went premium since then and I had had a taste of what "ultimate driving machine" felt like although in entry level only
When I switched to RX, the salesman emphasized the fact that I could use regular gas in it and I did for a while until lethargy became unbearable. Went back to using premium and fell in love with RX all over again.
Enter the NX. I WANT THE EXPERIENCE TO BE FUN, ENJOYABLE from the very start, so premium only for me.
I'm aware, this is all subjective but I am willing to pay extra for what I would consider fun and enjoyable.
So does premium make a difference? It does for me.
Conversely if your car is only designed for 87 octane buying the expensive stuff may do little more than increase your costs. “Putting premium fuel in our vehicles most of the time won’t make a difference,” said Juriga, adding that these cars typically have spark-advance curves that are tuned for regular gasoline and can’t advance enough to take full advantage of the extra octane.
Correct, if there is differences in numbers in those situations then maybe there is something real happening in their.Objective evidence is relevant in matters such as performance,say, how fast from 0-60miles for example. That's objective because it's measurable, but is there an objective measurement for what someone considers fun and enjoyable?
Thanks for the link. Read it and the gist seems to be: if your engine is designed for premium, use premium; if designed to run on regular, use regular.Saw this article and thought i would post it here as it seems pretty relevant.
