I guess this shows how many of us have become conditioned to think only synthetic is good oil. I have a friend who has a beautiful 2010 Mustang GT of which he takes very good care. He changes his own oil and enjoys working on the car. I asked him tonight what oil he uses, expecting him to say M1 or Castrol Edge or PP.
You fellows can imagine my surprise when he said he always uses "just regular Pennzoil in the yellow bottle." He reports it runs just great on that oil with no issues.
It's just strange that even I've become accustomed to thinking now that cars require full synthetic to have a chance of making it to 100,000 miles.

There's actually a possibility Pennzoil is using surplus GTL synthetic base oils in that product

PYB has always been a good oil...
I have used it for years and years the only reason i don't use it all the time now is i prefer an oil that has a safety seal underneath the cap to prevent tampering and leaks.
I have a buddy with 90s V6 firebird that he bought new after the Gulf War..he drove it all over the US a few times and has over 400000 miles on it changing his own oil with pennzoil 5w30 every 6000 miles. we did valve cover gaskets on it a few years ago and except for a little varnish it looked new.
I don't think I've read of anyone on bitog negating conventional oil's ability to reach 100K miles. But I completely understand your point. PYB, MS5K, GTX, QSGB, VWB... all can do the same for any vehicle which doesn't require synthetic. People just get caught up in...
'I want what's best for my engine'
'Oil is cheap, engines are not'
'I want my engine to be spotless with no varnish'
'because bitogers should be about the highest quality product'
On and on.
Engines have been going 200K-400K on conventional oil for a LONG time now....

Synthetic oils don't protect better...they hold up to longer ocis better. Imho
Besides...what does "synthetic" mean? We know so little about oil from a 25$ test.
other than long runs there is zero evidence so called syn out performs conventional of the same spec

If Mr. GT is using PYB 5W20 or 10W30, those oils have otherworldly specs considering they are conventional (or are they???).
The 3.5l V6 in my RAV4 mostly saw conventional and was still solid at 160,000 miles, but I did notice that super cold starts (pushing -30C) were better with full or part synth.
I use full synth in my FXT because it is a turbo and Subaru recommends it, just seems to make sense for that particular vehicle. I'm sure most NA engines will always be happy as clams on conventional.
I have an 06 GT when i bought the car the guy told me he had the oil changed at Ford dealer since he bought it. I drove it for maybe 300- 400 miles with motocraft oil and changed to Pennzoil 5w 20 for winter. The engine was smoother and and less noisy with Pennzoil syn....even my wife could tell the diff.... In fact today im going to summer mode since its in in the mid 80's already and using 5w30 Mobil 1 since Costco had such a good sale on it.
