Premium oils? Or just good oil for the money and performance?
I see products that work well and make sense financially or are better suited to my needs.
We have lots of vehicles with lots of drivers, and they are operated in a fairly demanding environment.
Oils that provide top levels of protection over the widest range of conditions with the lowest rate of oil consumption/ evaporation are perhaps my safest strategy and will likely produce the lowest cost of operation /ownership.
Even at 30 MPG we probably spend more than $9000 / year in fuel and over $8000 / year to insure all the cars.
Yet, with 7K OCI that is only 13 oil changes per year total. My cost for oil is probably $400+ per year.
Even if I used only free oil...I still have to buy filters, take the time to change oil, perhaps up to 30 times per year, and I run the risk that a driver will run low on oil and cost me many thousands of dollars.
Personally, I like Redline, GC, Mobil 1 /EP, Pennzoil Platinum, Delvac 1, Amsoil, Valvoline Maxlife, etc. etc.
Mobil 1 now costs $5.68/ qt and EP costs $6.22/qt at Wally World that's $6.20/qt and $6.78 /qt after tax.
Pennzoil Platinum costs $3.97 /qt or $4.33 /qt after tax.
GC cost me $5.00 /qt
Redline costs me $7.79/qt including shipping.
Delvac 1 5W-40 costs me $96.00 per case of 4 gallons or $6.00/qt
I can get some Pennzoil Platinum for $2.50/qt to $2.60/qt with rebates.
I can get Valvoline Maxlife for free with rebates.
I can't see where I decide an oil is 'Premium' based on price, only on performance.
I can see where an oil is a good oil based on my maintenance standards, the quality of the basestocks, additives, reputation... and likely performance.
So if I had to hazard a guess as to why people are switching to 'Premium' synthetics it is that they may cost a little bit more, but they can be worth it!
