Sometimes you come across a synthetic oil that has a GM 4094M approval, would this be OK, just as good for the 4718M requirement? I don't know what the new Vettes require, so do you think it is now 4094M? thanks.

What I did was to just cover the LTPS light with a piece of black tape. I know that at least one sensor must be bad, but how to figure that is a dilemma.

I keep mine in OD all the time. Regular D is probably better if you live in an area where there are a lot of hills. I live in an area with hills, but I still use OD.

When I bought my '85, the prior owner put on a Borla exhaust(and he worked for Mitsu). Sounds great!! Very intimidating at low speed and creeping around. When I get to highway speed, the sound goes down and very livable. Car has 60K on it now, bought it at 41K miles.

This may be silly to ask, but is this a current fix by a Chevy Dealer?? I know of this problem, would Chevy now fix it?? thanks

On a recent trip, in my '85, I was going thru the Carolinas & Va, when I decided to top off my gas tank. Now the outside temp was close to 100 degrees, my '85 was running great, did about 100 miles and decided to top off. I should have been able to put in about 5 gallons. I opened the gas cap...

I own a C4 and the GM code required for synthetic oil is 'GM4718M'. Is this still the code required for syn oil on your new C6 cars? Was it changed or an additional code added? I see the word 'performance' added to some synthetic oil products. thanks

The reason I'm asking is that I noticed that on some Syn oils they are using a GM code '6094'(?) and showing 'performance'. I was wondering if GM is dropping the 4718M code to a newer code for their newer Vettes. Or is 4718M still good for newer Vettes? I also have a Solstice, which requires...

When I started my '85 after a trip I made, the right side part of the gauge went dim. This is the side that has the temp/volt and below it has the mpg/avg mpg. This is the only part of the gauge that appears dim. The rest of the instruments illuminate fine. The car has just about 64K on it. You...

Thanks vetteoz!!

On my '85, on the back right side of the engine, between spark plugs, is the oil pressure sender(?). There is a wire attached, (green). How to remove this wire? The wire is attached to a plastic 'cap' on top of the sender. Which is the best way to remove it ( push-pull-twist?). I believe I have...

Saw a MT rendition, (tried to show what's under the cover) and overall it looks fine. An evolvement, but I just can't stand those Camaro-like taillights. Hope that doesn't happen.

My 85 runs fine at any speed, 62K mi. I find that when in stop & go traffic, I notice an oil smell, and sometimes see a light smoke coming from the hood, I think mostly from the right(pass) side. Do you think that my valve covers leak? Or maybe a bad PVC? Is it possible for the valve covers to...

I own one and it is truly a beautiful car. The maroon color is really rich looking. The only weakness is the optispark system, which can be prone to failure, in either miles or time with few miles. Some folks never have the problem, I suppose if the car is subject to a drier enviroment. I had to...

On the earlier C4's, like my '85, GM specs a PF25, but I have seen in up to date filter selections, a short type. I think the number is PF454, which is shorter, probably for more ground clearance. I have used both. Just wondering what you folks use. Thanks

I talking any LT4 equipped, because they all have the Grand Sport engine. I saw a license plate frame that had 'Grand Sport' and was thinking about getting one, but I have a CE LT4. Yeah, not the brightest idea for discussion, but just wanted to know how you all felt. thanks

I have an '85 that has/uses a single manual. To add sauce to the goose, if you want some out of print original manuals, Helm(official GM supplier) supplies a photo copy set of the manual, in white (single pages, not bound).

I was in heavy stop & go traffic, and noticed that when I had to give it some gas to advance, slow pace, I heard a clunk sound coming from the rear. It didn't happen every time, just when it went from a paused creep. It was warm outside, and this is the first time it caught my attention. Do you...

Not trying to lure you in, just to give you info: I noticed when I looked closely at the taillight lens(red) on my '85 it has a coding that shows that it is molded(?) modeled(?) from 1983. In the old days when you tried to tell the year of a car, when each year there was a distinction in design...

Maybe it's better they chew on the soap, instead of anything else :eyerole
