Oil Bible

Calestus · 01-30-03, 11:28

I searched the forum so this wouldn't be a repeat thread and i couldn't find anything so...

i was wondering if anyone had read this book

http://www.motor-oil-bible.com/index-test9.html

Its called the Motor Oil Bible.

I'll probably buy it later tonight, but was wondering if any one had any bad opinions about it? It sounds like a really good book..

Thanks!

I have done a lot of study on motor oils over the last few years. During the course of my studies I had occasion to read the Motor Oil Bible. In my opinion it serves as a good reference base for those interested in learning about maximizing engine lubrication. On the downside, the author of the book is an Amsoil dealer, and while his message is subtle, I came away with the feeling that it was written as advertising buzz for Amsoil products. (Not that there is anything wrong with Amsoil products.)

I read the book for free and felt good about it. I'm not sure I would have felt as good had I paid for it though. I will sum up the main tenants of the book for you should you decide not to purchase it.

1. Use a very high quality air filter and ensure that it is properly sealed in the air intake. The author recommended the Amsoil Foam Air Filter. My personal feeling is that you should use oil analysis to guage what filter is right for your application. I have shown better analysis results when using an OEM Toyota Filter than when using foam filters.

2. Use synthetic oil as opposed to dyno oil, and use oil analysis as a guide as to when to change it. I agree; in my opinion synthetic oils are superior to dyno oils in most applications. I currently use Mobil 1 SuperSyn 5w30.

3. Use high quality synthetic oil filters such as Amsoil's, Mobil 1's, etc. For the ultimate in protection add a bypass oil filtration system. Through oil analysis I have found Mobil 1 filters to be very good for my application.

Why are Honda and Ford demanding 5W-20 for their vehicles? Why does Honda say it's okay to use 5W-30 but to change back at the next oil change?

Why don't Castrol or Mobil make a full synthetic 5W-20?

What's going on here?

Your "only" oil question is 4 questions.

IMO, the reason manufacturers specify lighter weight oils is to improve mileage. With todays closer tolerance engines, the lighter weight oils seem to do an excellent job. There probably isn't much need for heavier viscosity in street engines.
Honda evidently doesn't fel that one change interval with 5W-30 is going to cause any problem. Remember, Honda engines quite often run well over 250,000 miles, so one change interval isn't much in their overall life span
Castrol and Mobil most likely got caught by the manufacturers change in recommended weights and have not yet released their 5W-20 versions.

I can't find the link to it, but a guy on the web did his own filter study. The offshoot is that there are only a few makers, and the best seem to be Champion Labs and Pure, both of whom make many of the other brands. For instance, Mobil filters are made by Pure. They are the filter just under Pure's top of the line Pure One. The one thing this guy reiterated over and over: Don't let your car even hear you speak the word FRAM, little on bring one close enough for it to see.
As for Mobil One motor oil, how about a Chevy Astro V6 that after 230,000 miles met compression standard. Started and ran like new, but the rest of the vehicle was on the death bed. I'm sure the other syns are good too. My new Toyota specifies 5W-30, and this is available in most brands.

mobil 1 will be coming out with a 0w20 fully synthetic oil that will be ford and honda approved for the 5w20 applications. For right now, just use castrol gtx 5w20, as it is 70% group 3 base oil instead of the usual group 2. Plus it has a lot of moly, which is an antiwear additive like zinc and phosphorus.

hondaguy2582 · 02-05-03, 01:43

the mobil 1 0w20 will be available the end of march.

AkronSi · 02-05-03, 01:44

I believe that Mobil is releasing a 0W-20 oil that is certified for all new Fords and Hondas that require 5W-20. It should be out soon, from what I hear.

WoW thanks for all the great replies. I like the motor oil bible and yes the guy is an amsoil dealer hehe.

ill be installing a bypass oil filtration system and also getting my oil analyzed before and after to see the dif.

im currently using valvoline 10w-30 SynPower i heard/read it was a bit better than Mobile 1

(insert a thousand flaming threads here)

I hope you don't receive flaming threads. I think arguing the merits of one oil over another is somewhat futal. Engine types vary more than vehicle types do. Even if one were to examine two like vehicles with the same size engine they wouldn't neccesarily get an apples to apples comparison of engine lubrication needs. A Honda Civic with 150,000 miles on it driven in Phoneix would likely benefit from diffferent types of oil than a Honda Civic with 50,000 miles on it driven in Minneapolis would for example.

I am a firm believer in using oil analysis as a guide as to what types of oils to use. Valvoline 10w-30 SynPower may very well be better for your application than the Mobil 1 SuperSyn I use would be.

BTW - What type of bypass filtration system are you planning to install? Keep us posted.

I read that one of the reasons for 5W20 is to reduce emissions in North America. That's why for the same engine, recommended oil viscosities are different in different countries

I agree with nightbird; www.bobistheoilguy.com has a great wealth of information on the topic of lubricaiton.
