Difference between Reg. Pennzoil and High Mileage Pennzoil?

I went to Wal Mart to get some oil so I could change it today and they had High Mileage Pennzoil for the same price as regular (mismarked). So instead of regular pennzoil 5w-30 I got 5 quarts of the HM 5w-30.

What is the difference between the two if any?

The High Mileage has a little higher VI base stock, a small amount of esters for seal conditioning, and the rest is the same additive package as regular Pennzoil. The High Mileage might have slightly more moly in it, but not sure. If Wal-Mart is selling it for the same price as regular 5W30, you got a good deal.
It'll be a slightly thicker viscosity than the regular stuff too. What car are you running it in?

I think the high mileage oils are a pretty good deal actually, they are a better oil than the blends out there, and are generally more able to maintain their viscosity than most $2 oils will.
I agree with pretty much everyone else. You essentially got a 25% discount on a good brand of oil ... a $2.00 per quart oil for $1.50 or so.

I'd guess the biggest difference is the ester content which makes this oil essentially a light synthetic blend.

Funny thing is, I think this stuff is better than most mass-market synthetics blends as they are merely Group II & III blends. No Group IV (PAO) or V (ester) in them at all.

I am running it in my 1993 Thunderbird with the 5.0L V8. The car has 88,000 miles on it.

My first oil change with the car I used Valvoline MaxLife and it didnt use any oil. The next change I used Redline and 3200 miles in, I was a quart or two low. I am hoping this will not get used.

Well, I am glad to know I got a good deal. I think I may actually stick with it.
