My favorite Chevrolet motors were the 283 and 327, followed by the 350. The big blocks today have no lead fuel and 93 octane max to operate. I spend an added 10 bucks for ZDDP to add to the oil so as to not lose a cam. I wonder if anyone with a 421 Pontiac can share my similar viewpoint on this? In the past we ran Super Shell and Sunoco 260 with leaded fuel, and used to be able to fuel at the airport long ago as well. It's bit much, paying 4.20 a gallon on 7-8 MPG, and it's the gas quality and then ethanol as well. I add Startron to prevent ethanol breakup. Today it's not so bad to run a small block like a 327 and not have detonation woes. Someone on here has minor worries about a quart of oil. Try dealing with fuel problems.
The comment wasn't directed to classics with minimal use of 2500 miles per year.
It was directed towards cars that were daily driven for every day use that accumulate 12-15,000 miles per year.
This is a 1966 GTO review; odds are few are ever driven daily. Secondly, classic insurance, which most would have, does not permit the car to be driven to work or driven daily. The oil burning comment is really off on this review.
If this is a 1966 GTO review, then what's the point of mentioning 2014 Corvettes?
Why talk about GM on a Pontiac review? And why talk about the same engines shared in the last GTOs, Camaro and early LS Corvette engines?
In the 60s and early 70s, the same size exact full frame platform was shared on 442 Chevelles, GS, and GTO by GM. At least Chevrolet remains today for both the muscle car and sports car enthusiast. I took what was left today.
Other than that, I would have to buy a new import unless I wanted to go to Mopar. It's nice to have a daily driver and an older weekender.
It's gotta be rare to see 2 GM owners fuss with each other. Anyone owning any one of these fine GMs past or near present should be absolutely ecstatic. Did I say own? Makes a huge difference comment wise.
GM actually had a Technical Service Bulletin for all 2001-early 2002 Z06s with an oil consumption problem. Faulty seals between the baffles and the valley cover lead to oil in the PCV system, which leads to the combustion chamber. This issue was resolved a couple of years later.
GTO LS1 and LS2 have been affected Using a quart every 2000 miles is considered normal. I change my synthetic earlier, so it's not an issue. I change once a year. If you have a Z06, it's a great car. And so is a 66 GTO. Have fun with them and don't fret.
Even if daily driven, topping off a quart of Mobil 1 between changes shouldn't be an earth shattering issue. These are now very popular transplants in older classics. I met a guy at an inter county car clubs meeting with 198000 on a 98 Corvette. That's a ton of miles for a sports car. The same engines are also used in late model GTOs.
I have been driving imports and domestics, and typically change the oil and filter every 5000 miles. It has been very common on most all of them to require a quart of oil between changes. I have truly driven many of my cars hard. To me, selected bursts once in a while in a remote area is part of the fun. Maybe I am missing something on this review about how much fun these cars are. Especially in my case owning convertibles. I love driving mine. Maybe others enjoy reading tech bulletins. I have learned a lot off YouTube videos.
Overall once you get a car well restored, there's very little involved with extra maintenance. I keep fresh fluids and filters gas treated, and keep it clean and immaculate. Put a battery maintainer on. I go in the garage, pull the cover and battery maintainer and go. If you don't have fun, I would buy a daily beater and point it to work only.
If you are never going to drive a 66 GTO far enough annually to burn a quart, who cares? You do I hope change your oil and filter annually. Even many late models in many cases aren't driven daily. There are many with ridiculously low mileage in my car club. It's not uncommon to see cars a decade old with under 10000 miles on them. They are toys.
