Cal proclaimed:

The I-6 doesn't have the ultra tight tolerances where a synth is pretty much required to keep lubrication film available. However, there is no real reason not to go either synth or synth blend at your mileage. If you get small amounts of leak increase you could switch brand, fix the seals, or add a bit of Marvell/STP blend. You can extend change intervals a bit with either swap. Might be worth checking the result by dropping a bit of the new oil out of the pan shortly after the switch to see if it is loosening crud--in which case just change it and the filter until that stops. I converted to synth blend at about 45K then just went full synth at about 70K and haven't had any leak issues other than that cheap plastic valve cover that went away on replacement.

Do you *need* it? No, your engine was designed for the older oils and their change intervals. Does it extend the life? Dunno--the engine is pretty long lived on ordinary dino pee with reasonable change intervals. Is it your engine and your choice? You answer.

Synthetic oils-Amsoil is as good as any-are a big benefit under the most severe temperature or duty cycle fluctuations, and under extreme stress provided the film is kept intact. The downsides are that seals for reciprocating engines are engineered for petroleum and not synthetic oils, also petroleum oils have superior contaminant bearing and corrosionproofing qualities.

Engines with substantial operating time on them should always be kept on whatever they are already on unless changing oils can solve specific known problems-and you are willing to redo the seals. Otherwise, wait until the engine is apart before changing.

Now you are showing yourself as a total fool.

The 'good as any' snake oil you are promoting will void any manufacturers warranty because it does not meet 'any' automotive standards.

Someone once gave me a case of the 'spamsoil' crap because no one was stupid enough to buy it from him, we 'like' our engines around here. I trashed it at the recyclers for him...

That said there are very few 'real' synthetics on the market. The makers went to court to get the definition of 'synthetic' changed so they could slap the synthetic label on anything weaker than raw crude oil that has been 'refined' and charge 4 times extra for the pretty label.

thanks for all the replies! I'm staying with my regular oil. I don't have any specific problem that I am trying to help, just wanting to keep my I6 problem free as long as possible!

I don't sell AmsOil. I have used their products, also Klotz and Bel-Ray and others, for specific jobs, and they all worked as advertised.

Aeroshell AD oil does not meet any automotive standards either but if you are running a pushrod gasoline burning air coold engine it's nevertheless the stuff to use.

You just have a hard one for Amsoil. The fact is that with specific exceptions it works okay or better. And it's less expensive and more available than specialist products like Bel-Ray or Klotz.

Actually he has a "hard one" for anything new

ROTFLMAO!

You think 'snake oil' is 'new', man oh man, it has been around since man first learned how to rip off man!

I just don't think we need people on this group that promote ripping off people.

Just because 'there is a sucker born every day' doesn't mean I have to tolerate the Scam artists. Especially slime like Spamsoil droids.

So any reason NOT to go for Mobil 1 (given that is what the Jeep dealer recommends / puts in if you are silly/lazy enough to get them to do it) ? Price is only a few quid more than the Castrol GTX Magnatec or whatever semi-synth; not worth worrying about.

Who are you, Mike Romain, to say what is and is not good? Amsoil has many satisfied customers and many of those have hundreds of thousands of miles of success with it. But yet YOU say it's no good. You have a seep seated psychological hatred for that company but they have never defrauded you. You know fully well in fact that their products most always work as advertised.

Amsoil may or may not be the best product or the most cost effective. But it is a product that is truthfully sold and in fact few people have any problems.

You are a goofball, Mike, and you always back up Bill Hughes no matter how stupid something he says is. You are in fact a lazy fat mountebank, because you want the benefits of a moderated newsgroup while being unwilling to do the work. You always blow your rear end about your idiotic charter, you didn't pay to invent the Internet, US tax payers did.

I'm seriously thinking of buying an Amsoil dealership just to piss you off.

Go ahead and buy an Amsoil dealership. I am sure it would tick Mike off. I'll bet Bill wouldn't like it either. I would be livid!

Go ahead and do it...

Ha ha ha ha. Good luck with that. :-/

Bret Ludwig proclaimed:

Yes, lets all hear it for Scamsoil. Why not bring in the fine folks from Allen Engineering and ask them what *they* think of Amsoil products. Or ask the Eastern District Court of Arkansas. Or ask Amsoil themselves why they had to sue Insurance Company of North America, Scottsdale Insurance Company, and St. Paul Fire and Marine to collect for the money they had to pay Allen Engineering.

He may also be aware that at best Amsoil is a MLM.

Be our guest.

You are a brain dead moron. API says spamsoil is no good. The vehicle manufacturers say they will void their warranty if you use it.

It is snake oil pure and simple and 'you' have no freaking clue who I am or what my past, if any, associations are with spamsoil droids.

Please get a stealership for them, they you can be gagged about it or have it taken away because they don't allow spam.

So far it would appear that you actually 'are' a spamsoil droid. Should we be checking with them to see?

I use Mobile 1 in almost all my vehicles since 1994. When I bought my YJ used with 189K miles on it, I switched it over to synthetic. Mobile 1 in the engine, Redline in the tranny, Mobile 1 synth AT fluid in the transferbox and Mobile 1 gear oil in the pumpkins. I now have put over 20K miles and it runs great. Of course the slip yoke seal was replaced before I swapped. :-)

Except my Diesels, of course. That's another story. :-)
