Reg vs Premium fuel?

[1MORLAP]

Use premium in the summer and 89 in winter. Temps matter.

Using 89 here while the the temps are in the 80 and 90's. When it starts to get over 100, I'll use 91.

Well, I was thinking that the 70 degress is teh cutoff.

Why?

Higher intake temmps require better fuel. Same reason your car is faster in cold weather - better air. Same reasons turbo car require premium - hot air.

I understand that...but why not run 93 all the time?

You should. But I think some people are looking to skimp. Therefore, it is almost acceptable to do so at lower temps. I always run 92 (all we have) here. But during the winter, I told my wife she can put 89 if it helps her feel like she is saving coupel buck for Starbucks.

I would not recommend that in hot weather.

Why pay more when it runs great on 89? If I work it hard (wheeling, road trips) I'll use 91/93...otherwise, more money for the $20 per week that I use for cleaing supplies (only so I can say how clean it is, washed twice a week, waxed 4 times a year....)
