im using 5w right now, but i want to switch to 10w-can i just switch it next time i change my oil? im not sure but i heard how you should flush the different oil before changing to another.

bronx99: i have 13+mi. right now and i want to change to synthetic- is 10,000mi a pretty good(ideal) time to change?

thanks

Some people change to syntethic after 3k *cough HRC *cough.. lol
But yes, it's recommended you change to synthetic after 3 oil changes. Anything after 10k should be safe.

As for changing from 5w to 10w, i know a lot of people who change to 5w during winter months, and 10w during summer months and have no problems.

Hey, why doesn’t everyone who’s interested in this discussion take a look at what Patrick Bedard wrote in Car & Driver back in November which started most of this debate about castrol Syntec. I found this link to his column on their site:

http://www.caranddriver.com/xp/Caran...mns_bedard.xml

I’ll have a proper response to Mr. Waterman’s letter a bit later.

Well, I finally got a good look at this letter and had the time to craft some comments and responses to what Mr. Waterman from Castrol had to say.
Quote:
... we conducted an extensive proprietary testing program that proved that the new hydroisomerized base stock allowed us to blend a synthetic product that was superior to the old PAO formula.
Superior? In what way? Have they compared the two in head-to-head tests? Oh, that’s right it was ‘proprietary’ which means private and not for public release. This smells fishy. If they have real testing showing their product having specific advantages (for our engines and not merely their corporate profits), why not make that information public? And just what ARE “hydroisomerized base stocks� anyway? Well according to the information on Chevron’s website (lets call them an uninterested 3rd party for the sake of this argument), they are all heavily processed oil-out-of-the-ground oils even though they refrain from using the terms ‘crude oil’ or ‘petroleum’ in their descriptions. These words probably have very specific definitions within the industry even though lay people would use them to describe all that black gooey stuff that comes out of the ground.

http://www.chevron.com/lubricants/main.htm

Quote:
Rather than attempt to compete in the marketplace, Mobil - a major manufacturer of PAO base stock - challenged us before the NAD.
Actually it was presented to me that Mobil had sued Castrol basically over the word ‘synthetic’ ... and the lawsuit went nowhere because there is no standard, accepted definition of the word ‘synthetic’ as applied to motor oils. Every processed product where molecules are rearranged to one degree or another COULD be called ‘synthetic.’ So, the National Advertising Division of the Better Business Bureau could not rule against Castrol for false advertising. Just because it is ‘legal’ doesn’t make it right. We all know THAT.

Quote:
The challenge backfired when the NAD, relying on industry standards and the
extensive expert testimony of leading scientists here and in Europe, rejected Mobil's position and completely upheld our position.
Again, just what IS ‘synthetic?’ The problem here is definitions ... just like the tricks Slick Willie used to weasel out of trouble.
Quote:
As the NAD found, the assumption of both Mobil and Mr. Bedard that there is only one way to formulate synthetic motor oil is plain wrong.
This is pure BS. They never said that. Redline uses Polyol Esthers and there are other synthesized, non-petroleum/crude oil lubricants out there that would qualify as ‘synthetic’ easily. Mr. Waterman is putting silly words in other people’s mouths and he should know better.
Quote:
Mr. Bedard's article includes several significant mistakes:
1. Syntec is made with "petroleum base stock."
Syntec is not made with petroleum base stock. Just as PAO is derived from
complex chemical reactions starting with ethylene gas, Syntec's base stock is synthesized using sophisticated processes and chemical reactions. The molecular structures of the starting compounds are fundamentally altered to produce a fluid with vastly improved properties capable of attaining the highest levels of formulated synthetic lubricant performance.
OK, he talked about where PAO (Mobil 1, Valvoline Synpower, etc ..) Comes from but he fails to say what Castrol Syntec started out as. Tree sap? Cheese Wiz? Toothpaste? The truth is it comes out of the ground just like conventional petroleum oil. Perhaps it’s not TECHNICALLY called ‘petroleum’ once it’s gone through certain processes, but it comes from crude oil just like petroleum does. These arguments are merely silly semantics.
Quote:
2. PAO results in a more stable fluid, with low temperature flow, and resistance to boiling off and oxidation. The inference here is that Syntec's base stock does not provide these properties, which it does.
All companies make these sort of claims and nowhere on Mobil’s site, sales literature or packaging do they disparage any Castrol product. Mr. Waterman can ‘infer’ all the bad things he wants but he’ll get precious little sympathy from me.
Quote:
Syntec's performance in these areas is unsurpassed.
Really? Let me see the test results. If Castrol’s stuff is truly better, I’ll switch in a couple weeks ... the next time I change my oil & filter. If this new way of making lubricants was truly better for our engines, Castrol would have spent millions in advertising pointing this out to consumers. Their lack of evidence says a lot about their product.
Quote:
It meets the toughest industry standards.
Yes, and so does all the no-name brand oil that says “SJ� on the label. As we all know, this doesn’t mean squat. The only ‘high-performance’ standard that Syntec meets that regular, conventional doesn’t is the GM 4718M Corvette standard and I don’t know the specifics of that at all. It may be something minor that allows Syntec to slip through while excluding other high-performance petroleum-type oils ... like the fact that they claim to be a ‘synthetic’ while the others do not.
Quote:
3. Syntec's base stock costs half as much as Mobil 1's.
Mr. Bedard quotes a statement from Lubricants World that does not pertain to the base stock Castrol buys for Syntec. In truth, Mr. Bedard has absolutely no information about the production costs of our product ...
Notice he doesn’t deny the charge that Castrol’s newer formulation is cheaper for them to produce and they’re now making a fortune off the stuff? Patrick Bedard’s primary point is that Castrol switched over because the newer formulation is cheaper to produce ... and nothing Mr. Waterman has said has dissuaded me from that central supposition.
Quote:
Syntec is engineered to surpass the minimum performance levels specified by U.S. automakers for the mass market.
See above, nearly ALL oils sold today meet these ‘minimum performance levels.’ Big deal.
Quote:
We trust that his article will not mislead you and other knowledgeable consumers.
Yeah, well blowin’ smoke up our butts doesn’t change the fact that you guys are selling highly refined (“hydroisomerized base stock�) crude oil and telling us it is essentially the same as specialized PAO and other AUTHENTIC synthetic formulas. If you want a high quality, petroleum-type hydroisomerized oil, do yourself a favor and get Valvoline Max-Life motor oil which can be bought for $2 per quart as opposed to the $4+ that Castrol charges for its Syntec.

I’m a ‘knowledgeable consumer’ and all I saw in Mr. Waterman’s letter is a bunch of lawyer-speak. You can fool all of the people some of the time and some of the people all of the time but not this boy ... not today!

Thanks Mr. Waterman, but I’m sticking with PAO-type synthetics like Mobil 1, Valvoline Synpower and others (maybe even Quaker State?). Plus, this summer I’m gonna try Redline which is probably the best stuff on the planet ... then all this other arguing will be moot.

--- Bror Jace

PS - If I can find an e-mail address for Patrick Bedard, I’m gonna fire this letter off to him and hopefully get some sort of response.

OK this post is amazing.
I will put it in the FAQ tomorrow as I want to see if anything more is going to be asked.

Amazing !?
It could be summarized to:
-Is Castrol Syntec too expensive ?
-Should synthetic lubricants sell for more than petroleum based oil ?
-Will our engines live longer ?

Thanks Joon for posting in the FAQ.
Thanks Bror Jace for your reasoning.

I find this stuff fun and interesting.

I just want to say for the record that I don't work for any oil company, any agent, subsidiary or affiliate of an oil company, etc ...

The only work I've ever done in the area of the automotive industry was working as a traveling sales rep for Cantex/Mintex which riveted disc brake pads for the Northeastern US and the subsidiary I worked for went belly up several years ago.

You guys ever heard of Amsoil? I just swithched to it because I found out that Mobil 1 isn't 100% synthetic. I'm using 0W 30 with the Amsoil filter.

Amsoil isn't necessarily a BAD oil in my opinion, but there's a stigma attached to it because of the multi-level marketing way it's sold. The joke is that it has more dealers than customers... kind of like Amway although I don't think they're related.

Amsoil's main ingredient is PAO ... just like Mobil 1. They supposedly have a number of other ingredients, many of which are 'proprietary' ... a fancy way of saying 'secret' ... and I'm a little distrustful of products that are less than forthcoming about what's in them. Highly touting 'secret, space-age ingredients' is usually the first sign of snake oil and that ends me fleeing in the other direction.

I was talking to a guy and racer (SCCA, I think) on the use.net forums and he said that he and people on his team followed up on some of the testimonials that Amsoil listed and the people (I think it was a police department in the midwest) would not admit to even using Amsoil or hadn't used it in years and could not verify the claims of increased mileage, etc ... I find Amsoil’s testimonials and the testing shown on their site to be suspect at best. I don't recommend people stop using it, but that stuff isn’t in my top 3-4 choices. They use to use some oddball formula over a decade ago and when it led to some engines getting damaged, they blamed people for not properly 'prepping' their engines before switching over from other oils. Then they radically changed the formula to PAO which most people use as a basis for synthetic motor oils. Keep in mind, they radically changed what they were selling ... but the hype remained the same. Anyone else find that odd?

From what I know, Mobil 1, and most other synthetic oils that say 100% synthetic on the bottle are indeed 100% synthetic. The term 'carrier oil' comes into play here and that has been explained to me as essentially traces of petroleum oil that have been used in the production of some of the ingredients. They do not appear in the oil in significant concentrations and I wouldn’t let that term frighten you away.

Mobil 1's newer formulation is called "tri-synthetic" as it is supposedly PAO (still the main ingredient), some synthetic esthers (like Redline) and a third ingredient I don't know anything about.

As for 0W30, I’d pick a formula with a higher base number ... at least a 5W30 because of the STP-like goo used to bridge the gap between the winter and summer numbers that can clog up your motor with sludge and varnish over time. If I lived farther down south, I’d be tempted to use strictly 10W30 because most synthetics in this weight contain no ‘viscosity improver’ (VI) at all.

I don’t know anything about Amsoil filters except they buy them from some other manufacturer ... and I believe their claims are misleading (just like Fram’s).On Hondas and Acuras, I’ll stick with the OEM (Filtech) filters. On other cars, I’d be tend to use WIX, NAPA Gold, Hastings, Purolator Pure One, etc ...
