That article, although long, does a good job of putting complex oil descriptions in to common language. Good read. I'm sure it'll spark debate, especially the AMSOIL part...
 
Wow... There is a lot of info to digest. I wonder about the recommendation to change the oil at 200, 500, and then every 1000 miles, until 12K, on a new engine... Sounds good, but wonder if it is really necessary on our CTD's... :confused:

I do it on my motorcycles... but I do it at 300, 600, 1200, 2400, (or every other trackday) but 14k rpm can be a little harder on oil... :D
 
I remember when we rebuilt motors in the 70's we would start up the new motor and get it up to running temp then shut it down and drain the oil ,put new oil and filter in. makes sense
 
J... One really great READ... As i have been changing my oil and filter right from new at 800, 1100, 1300, 1500, then 1000, 2000, once about 2800. Thanks for the good info in this read!

It is a great read, but I'm not to sure about him changing over to Mobil 1 in his '71 429 Mustang and gaining 7-8 mpg. Maybe it really happened, but to almost double your mileage by simply changing to a different oil seems a bit far fetched. But it is definitely a very informative read. Thanks for the link.

As a side note, I'm interested if anyone can contradict his comments on Amsoil with some real technical data as opposed to his favorite, Mobil 1. I know that there are a ton of Amsoil users (myself included) on the TDR. The author had no data to support his stance on Amsoil, just his personal views.

I'm surprised this thread isn't getting more attention. Is it just me or is everyone just sick and tired about discussing oil?? I thought the Amsoil part was going to really stir the pot.

Interesting, couple things that I would question on the article though. Right in the first paragraph he states it take 5 minutes to build oil pressure, maybe he meant 5 seconds, no way 5 minutes.

I have a oil temp gauge on my engine, the oil runs between 215 and 230 degrees when the engine is at operating temp, he lists oil running at 150, I do not think any oil in a modern engine runs that cool, it is impossible, as the coolant is over 200 degrees.

All the break in information focusing on 12k miles, mileage is not a good yardstick of engine wear, it could be 12k miles of city driving or 12k miles of cruising on the freeway, that is why many makes have gone to oil life monitor systems that take into account rpm, load, temp, and other variables.

As stated above 7 to 8 mpg gain just from switching to synthetics, no way, if that was the case we could practically solve the oil shortage by having everyone switch to synthetics.

Modern engines do not have chokes or carbs which greatly reduces the issue of fuel dilution in oil.

I also doubt the cars in Europe have longer drain intervals than cars in the US based on driving style, they have all the same traffic problems we have, in some places worse, it is not all driving on the Autobahn at 150kph, not to mention most Porsche and Mercedes use engine life monitors they do not have set change intervals based on mileage, only if a certain amount of time has passed, like a year if the monitor has not indicated to change it.

He does not like Amsoil because they claim extended drain intervals, but he does like Mobil1, wonder what he thinks now that Mobil1 is offering extended drain interval oils?

Interesting information, as always though just because it is in print on the Internet does not mean it is correct.
 
Arguing about oil brands is like competing in the special olympics. Even if you win, you're still retarded.



It's all the same for me. If it's rated for the engine and it's slippery, down the hatch it goes.
