Have you ever heard of John Sawruk? John was the foremost Pontiac expert. John recommended NEVER use synthetic oils in these old motors. He touched on the reasons why at seminars he gave. He didn't touch on this topic at the seminars of his I attended but others I know did and learned why not to use them.

A local performance motor rebuilder also recommends not to use them.

Many swear by the synthetics in these motors. I opt to listen to those like the late John Sawruk and heed their advice.

66tempestGT it might just be me, but i dont order steaks and eat two bites and throw the rest away. i dont use a couple paper towels and throw the roll away. i dont take a couple showers and throw the soap away. i dont watch a few shows and throw my tv away. but maybe i should, better safe than sorry right?

if it was perfectly good what did you accomplish by changing it? i run synthetic in my mercedes and change it at about 15000 miles. i change the filter every 5000.

68greengoat Yep, oil is cheap compared to a rebuild. And you can't put a price on peace of mind.......

GTO JUDGE I'll change oil in the spring and run all season with it approx 1500 miles.
Right now: Castrol GTX 10W40 / ZDD+ additive / AC Delco filter.

Is it perfectly good oil going down the drain? Yea, probably but keeping it fresh will help with this 41 year old motor. The interior was spotless when it was apart and if throwing good oil down the drain after driving it 8 months and 1500 miles or so then for me its peace of mind and I'll keep it fresh. Just my .02.

GTO JUDGE I dunno what the total ratio of ZDD+ is to 6 qts of oil included in each quart but:

I use one 4oz bottle of ZDD+ per 6 QTS Castrol 10W40. This is adequate according to the bottle. I would think 4 ounces of ZDD+ per pre-mixed 6 QTS oil would suffice. This equates to just over 1/2 an ounce per 1 qt bottle of oil.

85_SS The VR-1 I have states on the bottle that it has a ZDDP additive in it for "tough anti-wear protection". When I was researching, the VR-1 was one of the higher recommended oils - I don't recall the ppm numbers off hand, but they were sufficient for a flat tappet cam.
