Mobil 1 0W40 is OK but their Formula 0W40 FS.
The problem with Mobil 1 is you have to look at the specific Mobil 1 xxx.
Here is the list:
I like the specs on the Formula FM or Turbo Diesel Truck 5W40.
Personal opinion.

I am surprised Amsoil or Royal Purple hasn't come up on this thread, I know everybody has some brand of oil or another they are loyal to, I tend to believe what I see. Years ago I went to a local machine shop/engine builder that does CNC machining, this shop builds a lot of Saturday night special pro-series engines and the builder showed me engines that run on most of the available oils, only the Amsoil engines looked like new at the end of the season and needed nothing but routine freshening up, he stated one engine had over 6000 laps on it and still didn't need anything also showed almost no measurable wear. I have a friend that races stock cars his engines were built by that shop, my friend backed the car into the wall one week and broke the rear main bearing cap he didn't know until after the next week of racing a complete feature race, his engine had almost no oil pressure he thought it was an issue with the gauge yet the engine ran fine and showed no wear because of Amsoil. I have been running Amsoil in everything I own with Wix or NAPA filters for 20+ years and will use nothing else. By the way that engine builder said Mobil1 was garbage and showed me an engine that ran it he was right. I haven't rebuilt my AMC engine yet but already know what oil will be in it.

I too am an Amsoil fan.  When my wife's Plymouth Laser with a Mitsubishi 4 banger blew its timing belt, I had to have the head off because of bent valves.  With 250,000 km. on the engine, it was very clean inside and still showed the factory honing marks on the cylinder walls.  Had used Amsoil since 6,000 km onward.

What is wrong with Brad Penn (now Penngrade 1) oil? I've been thinking about switching to it myself.

Currently using Rotella T 10W30.

My link shows Amisol is tops, and with detsils as to why. Others come off pretty good as well. Just the big question made, was not to break the piggy. Top oils are expensive, and may not be worth the investment on a street driven car ovrr other brands.


I know the link i gave is huge on the topic, and can loose some in that it is written out kinda like billd would expain.

I doubt any street driven car would benifit on the best of the best oils, as demands on the engine are light compared to full track time demands. Though anyone will change to the proper oil before doing so, as it is common sense.

You may find the list of oils eye opening, as there are a few over the counter oils thst come close to being just as good as racing oils. And the only issues with use, is hey have a higher drop off with higher heat range. The Mobil 1 oil is not common in the states, but may be found in Canada and Mexico. Like explained in a previous reply, not all Mobil 1 oils are made the same. You must have a keen eye and specifically obtain what was tested. Even oil weight selected6 can effect the same make of oil, as the engineer explains in details with additives and components jn the oil make up, that may effect how ut performs. Some perform better with additives some dont gain much all.

I recommend reading through the long bits, as to see how oils stack up, just because one is better, does not mean the few below it are not as good for a street / strip driver.

Amsoil signature oil is good for 25K at a cost of about $60 per 5 quart oil change + filter, I don't know anyone who drives their classic ride more than that in a year. Not having to crawl under my daily ride more than twice a year (Amsoil recommends changing the oil filter at 6 months) saves me time and hassle ends up with a comparable cost and the best protection. I run Amsoil in almost everything cars, lawn mower, snow thrower also use their 2 cycle oil. The best way to solve a problem is to not have one, saving a few bucks on low performance oil doesn't seem to pan out when it comes to distributor gears.

Check the cam gear and make sure it's delivering oil to the distributor gear as it should. That is the #1 reason for chewed up dizzy gears. Make sure you have a MATCHED SET of gears, preferably used AMC issue gears, but especially aftermarket replacements need to be a matched set. The added oil line will help, but corrected cam gear oiling is usually more than enough. If you have high pressure/high volume oil pump mods that puts added pressure on the drive gear also. Not really needed in an AMC -- the stock pump provides more than enough oil and pressure with just some cover clearance tweaking.

I believe this is the page 304-dude is referring to:

I've read through this and there's a lot of information there. The author makes the point (many times) that ZDDP isn't the only thing to consider as far as wear is concerned. "Film strength/load carrying capability/shear resistance psi value" is the measure of wear protection according to the blog.

Some of the Amsoil oils as well as 5W30 Joe Gibbes Driven LS30 performance synthetic looks pretty good too.

The set that got chewed up was a matched set of original AMC gears. The only variable between that engine and the previous one was the type of oil used and the timing case was an aftermarket piece that was machined by an AMC vendor. This is the ONLY engine I've had with this problem.

After I assemble an engine I prime the oiling system and look through the fuel pump window to make sure the distributor drive gear has oil flowing out of it.

Yep, but i did reply in this topic with the same link within another oil thread, its located at tge end of the opening page on the link.

Its an on going oil test that has some oils no longer being produced, which still are part of the list. So its a huge compilation of sorts.

Just because one brand may seem as standard, there are key differences in each product subset. I never knew that Mobil 1 has more options off the shelf than what is advertised or usually picked at the store.

Believe it or not a high milage oil gets pretty good score for not being a performance oil. Trouble is you must keep within the heat range. As it and others will drop in protection by 28%.

Just keep point that a brand makes a good known product and a not so known excellent product that may look similar by packaging. Example the new Penzoil Platinum is not the same as the old Platinum, which was one of the tops on the over the counter oil. I had two 5 quart jugs that i purchased for our cars. One was 30w and the other was 20w, only the 20w was the the original platinum, while the 30w was the new oil. They looked almost identical but the new oil had a logo for the blend to show it was not the same as old type.

Though it was a one time deal, so that said, i am back to Mobil 1, which actually runs cleaner with a 1 micron filter used in conjuction. Purolator finally fixed their product line... some time in 2011 or so they had issues with their top of the line filters. STP, Mobil 1 and Wix still are good 1 micron filters.
