I run Brad Penn in my hot rods, including my race cars (30w Break-In in the new gas builds, either 10w30 or straight 30w or 40w in the gas engines, and Nitro 70 in the alcohol engines). I run Amsoil 5w40 in my diesels.What are you guys using in your cars and what type of motor are you running?
Up until recently, that was one of the better off-the-shelf, readily available oils that had decent levels of ZDDP. With the increase in diesel emmissions equipment, and oil requirements following suit (just like the gas engine oils), that is quickly decreasing, too.I use, ok ready, shell rotella T. Yup, diesel truck oil in my nova. Dont ask why. LOL JR
X2...also, if you can read some of the information George Morrison (RIP), a dear friend to the lubrication industry, published. Another resource is www.bobistheoilguy.com. As a lubricants retailer, these are a couple of sources I often refer.Not long ago VENO started the thread "ZddP and modern oils". The information in that thread is INVALUABLE and much of the information in there VENO acquired at his own expense. It should be required reading for everyone...especially for those running flat tappet camshafts in their engines. In short, new does not mean better. Modern oils no longer offer the same wear protection they once did all in deference to the EPA.
Also included in that thread are other links. Those links are just as valuable. Take the time to read them. In doing so you will learn why it is NOT a good idea to use "racing" oil in street driven vehicles; why it is NOT a good idea to use diesel oil in gasoline engines and why it's NOT a good idea to use synthetic oil when breaking in an engine. The scientific information is all there.
The good news is there are some oils out there that remain (almost) unchanged. There are also oil supplements that can offset current formulations.
And, finally, you will learn how to read the oil "classification" information on the back of the oil you purchase so you have the peace of mind of knowing you are purchasing the right oil for your vehicle.
Take the time and do the homework.
