Don you can lead a horse to water but you can not make em drink. You have helped many others that understand.

Now you know how I feel on some of the brake issues and false info that some refuse to let go.

Good job!

 

I know what you mean. Oil debates are as bad as religion and politics.

You have the facts that are accurate and then you have those who only trust what they were taught 25 years ago and discounting changes in the auto industry and advancements of oils.

Then there is the Amsoil heretic that always drops in at some point.

I too use Mobil One with great success for many years. It has been upgraded and adapted to the new standards. required by MFGs.

The funny thing is so many want to argue but most can not tell you want any of the codes and API ratings on the bottles mean or stand for.


Here is something we all should read. It has something for all to learn.

Ok heres a question for the "experts" - I have a case of amsoil OE synthetic, I have read that a flush is required when switching from conventional oil. I have been using mobil 1 full syn for a long time now, do I still need to flush it out going from mobil 1 to amsoil synthetic? I dont plan on staying with the amsoil as the mobil 1 is much easier and cheaper to get around here.

 

I'm no expert but from enjoying years of debate here is what I remember. Well I'm old so I think I remember lol

In the beginning Mobile 1 was not fully compatible with Dino based oil so a flush was needed,, Today the new formula is made to mix with Synthetic and Dino oil. So if you used full synthetic and need oil while on the road you can use dino oil to level up! AMSOIL oil as far as I know is a top teir oil and should be able to mix dino with synthetic so no flush should be required,, I think on the AMSOIL site there is a Q&A section that will answer your question 100% or we have a Dealer on site who can help..
Will you see more MPG from synthetic oil? minor at the best.. On my bikes or cars I never really noticed...
BUT when I used Mobile 1 on my 6hp lawn mower I did get to cut both sides on 1 and vs. a refill to finish, so maybe a bigger difference on a air cooled motor so I guess I got more yardage :O

 

Good link thanks, I book marked it! And THANKYOU to all who post link's and offer input taking your time to help us!
Also the debate which is better Blonde's or Brunette's or
Big Boob's or Med boob's or small boob's

 

It is easier to sell to one of their disciples and just stay with Mobil One.

Not casting an evil eye but the fact is Mobil meets or exceeds all you or the MFG needs and you can get it anywhere are key selling points.

If it ain't broke why fix it.

 

The only debate here is if you read entire paragraphs or just the phrases that you want. I just don't know why I bothered quoting entire sentences, when evidently only 2 of the words are actually there to be read.

GM says "DEXOS is DEXOS". They have an entire lab set up to make sure that any product with the DEXOS label on it, and a license number is the same as any other with the same label and a license number.

One of the things that the DEXOS spec does is replace the API specs. They may still be there, but not all oils with identical API codes are DEXOS.

 

and so the story closes with please use the mfg recommended lubricating fluid and change it when the DIC tells you to. very simple very concise, and for the record Radco, any size or hair color will suffice as long as she likes HHR's lol

 

Or easier yet just use Mobil One.

 

This statement MAY lead to some confusion ^^^^^^^. dexos approved oils are FULL synthetic or synthetic blend......depending on what is required/commended by the vehicle manufacturer. But GENERALLY, turbo, supercharged and TRUE hi-performance cars are recommended/required for full synthetic.

In short, any dexos approved oil that is full synthetic will be ok in any GM car. While the synthetic blend, dexos approved oils are not recommended/required for those vehicles specifically calling for FULL synthetic.

I believe Mike mentioned this in post #6 of this thread.
