I'd rather pay for a Mobil or K&N instead of the cardboard junk. they handle heat better, don't brake down as easily, many advantages other than a couple extra thousand miles.įirst opportunity on my now 1 week old 86 PU 22R, it's getting Mobil 1, and Royal Purple throughout.Ĭost is not an issue for me, not the relatively minor cost difference. Full synthetic, not blends are a better oil, Period. Almost all FLEET vehicles, the Government and Military and new vehicles all spec synthetic. The older oil was just hiding potential problems. If the cleaning action of the oil opens up leaks in gaskets, they needed to be replaced. I have used Mobil 1 on high mileage Jeep 4.0's for a long time. Much of the BAD hype about synthetics is just that. I just haven't been convinced that they are so much better than conventional oils for my 1993 truck that I would be swayed to change from the 3000 mile dino oil changes I've been doing for the last 22 or so years without incident.
However, from all that I've read, it seems there is little benefit given the cost of the oils for normal engines operating at normal temperatures. I've read some articles from independent sources as well and they do confirm that the synthetic oils offer some benefits in high performance race engines that operate at extremely high temperatures.
(NOTE: I took a couple of marketing classes in college so I am a little sensitive to anything a marketing entity tells me. Most of the "mythbuster" and "why use synthetic" articles are written by the very same oil companies that manufacture the oils (or their marketing firms) and want you to buy them because they make more money on them. In my opinion, they are not usually worth the extra cost, in some cases 3 or 4 times as much as conventional oils.
The main problem I have with synthetics is the price.
