My vette has 175K miles on it. I have been using synthetic oil with every oil change. My mechanic says it is okay to use the synthetic blend since my car has such high mileage. What do you think? The real stuff or the blend? :huh:

Yep. I'm not sure about the '86 but my '92 doesn't use an external oil cooler. Because of this synthetic oil is recommended and that's what I use.


Besides, isn't the cost of the blend about the same as straight synthetic?

Never used synthetic oils in my '86.


Of course, I've only owned it long enough to do one oil change! :laughing:

Yes, I was thinking along the same lines, but went with my mechanic's suggestion. Next oil change, I will go with the real, good, more expensive oil. :laughing:

I agree, next oil change, back to the real stuff....My mechanic thinks I will spend too much in repairs. Hey, it's only money and I love my car!!! So far, no repairs in six months!! That is becuase I spent about $3K in repairs last year, some necessary, some maintenance. My car runs great...and looks darn good. ;)

Can never go wrong with this. Much cheaper than an engine job.

BTW, if I was driving an old Taurus (cough choke) or something... Then I'd put any old thing in there..:thumbsup:

Sorry, I shouldn't have brought up anything to do with that four letter "F" word on a Vette forum. I'll try to keep my cuss words down from now on..:devil:

I have built 3,,, 485-fwhp, 406 engines in the past 4 years, using good old 10w30 and the syn/blend works fine,,, for an engine with that many miles, I would use a high mileage motor oil

The only risk you take is the synthetic oil molecles are smaller than the carbon based oil. These molecules can find and fit through small holes in your seals the carbon oil cannot. Keep an eye on your oil level and you'll be good for years to come!

My 1988 vette leaks a little at the rear main. So does the 468 big block in my camaro. I use Mobil one in the vette but not in the camaro. Reason being the camaro never runs at the high temperatures like the corvette. We have all seen the commercials showing oil breaking down with heat. When I bought the vette last September it had regular oil in the engine and it leaked a little then but it doesn't leak any more with Mobil one, I plan on rebuilding the engine myself this winter and fixing all the leaks. But I will still use Mobil one in it after the rings are seated on the fresh engine because it will still run as hot or hotter thanks to the wizards at GM:devil:

I use Redline 5w30 in my LT1 and have been since 112,xxx. I change it every 15,000 miles. At 7500, I will change the oil filter and add a Qt. I use K&N oil filter. Car has 203,xxx and no problems. Since I do sell Redline at my shop, I do get a slight price break, but it sure is easy and cost effective to run that brand. The 9hp gain on the dyno was a plus also.

Yes, mine has a leak that I have not yet fixed. I do keep a close watch on the oil level since the digital display is slowly dying....
