Replying to: lvhatchbk (Jul 15, 2008 9:49 am) Even though I know what you mean, your question highlights a common point of confusion: the difference between "recommended" and "required" when it comes to octane.   If the word "required" is used, end of story. A 91 octane requirement is a hard stop. Of course you are free to go higher, if you can find it and are willing to pay.   If "recommend" is in the language, then things are different. In many cases, 91 is recommended (small print: for best performance) but usually there will be a sentence saying that 87 can be used without a problem. The higher octane fuel is needed to achieve the advertised horsepower and 0-60 times, but the engine and its controlling software can handle 87 octane, just fine.   If the manufacturer wants to advertise the higher horsepower, the common practice has been to "recommend" the higher fuel and allow the lower grade. I'm not sure if there is a legal requirement to do this if they want to advertise the higher horsepower rating, or not.   The G8 falls into this boat. Premium is necessary to get the advertised horsepower and performance, but the engine is designed and calibrated to run reliably on 87, too.   In recognition of the public's recent concerns about fuel costs, GM has changed the wording a little bit. From the GM media website, with respect to the 2008 Pontiac G8...   "Recommended fuel: regular unleaded (premium maximizes performance)"   This flexibility isn't universal across the board, however. Many cars have the word "required" in their owner's manuals, and they mean it. Severe detonation could occur in these engines, causing damage over the long term that would cost much more to repair than the savings incurred by running fuel 87 in them. But the G8 isn't one of these cars. Replies to this message: lvhatchbk (Jul 15, 2008 2:17 pm)

I would buy a G8 GT tomorrow if it was offered with a manual transmission (not just in the pricier, less fuel efficient GXP version). I will probably get a Mustang instead, even though I would prefer many features of the G8. Auto trans is a deal killer for me, and I imagine many performance seekers.

Replying to: jpstax1 (Nov 04, 2007 11:10 pm) Yes, Having Onstar, is a great feature to have. I just found out, since I am a new GM car owner, that I can call onstar and they will book a hotel for me if I am on the road, and have it ready when I want to stop or arrive at my destination. Also, its great, if I need to find a starbucks near they highway, they look one up, and off I go. They can also look business phone numbers for me. Look for any attractions that I might miss in an area. I am currently trying the 3 month unlimited for $20. I will see how things go with it, but so far, very impressive! The nice thing about this, is that you can pay as you go, rather than get a $1-3k navigation unit in a car. For the life of the lease, is it really worth it, and does it really offer the seemless options of Onstar. I don't even have to take my eyes of the road, they do all the work for me. That is almost worth having a GM car, but would it keep me in a GM car, I am not sure, their are many amazing great cars available, and do fine without Onstar.   Would I opt for the navigation unit in the car? I might, should all car be standard with it? Yes, I think so, it would help us all out, this day in age, they should be making a economic way of making Navi standard in atleast all your premium trimmed cars. but, even Onstar stated, people usually don't use it when their in the home town. Acura is making a really nice navi, that makes it a entertainment center. Offering alot, and that makes it more worth it.

Replying to: svtguy (Jul 15, 2008 5:03 pm) I see that many companys are getting rid of their manual transmissions. They are going to the Auto with the shiftronic, but nothing beats a manual. Its a true performer!   Imagine a G8 V8 with a manual! My co-worker has a Charger R/T and its an automatic...lol Crazy thing too, she lives like down the road from work, I hope she takes that bad boy out and runs it wild every now and then. I know I would!   I truly love cars! Paint, all the way down to the engine. I always keep my cars washed,waxed, down to the tire shine. It makes any car, when its kept up, look that much better! Like a black car, with someone who takes care of it, looks amazing!

Replying to: circlew (Jul 07, 2008 4:34 am) Ha! Some of us leased 2004 GTOs for two years at $121/month with no down payment, so it can be done if the incentives are right   My local dealer has 35 G8s out of the sudden... They look real nice lined up next to GMC Sierras and Yukons. I'm just waiting for Christmas and $5K GM card incentives - I may bite then... I saw the $3K market adjustment on the sticker just the other day, so these guys may intentionally drive themselves out of business. I heard that selling used cars is all the rage these days.

Replying to: cracovian (Jul 21, 2008 9:15 am) Good feedback...I wouldn't touch one of these for a long time...wait for inventory to build. Then follow GTO logic.   I guess the dealer business geniuses don't see the price of food and energy building. No problem taking on a 10% profit right before your eye's, right?   Hey, if the unions can do it why not the dealers?   Regards, OW
#843 of 961 What's the depreciation... by circlew Jul 21, 2008 (10:37 am)
on a G8 GT? I assume if you pay$40 plus, it's worth $35K as you drive it off the lot.   Regards, OW
