Just put in Mobile 1 Extended Life 10W30 oil.......

[redmanfx]

..... and will be seeing how well that does in the Q. It's about 50 cents more then the reg Mobile 1 motor oil but I thought I would give it a whirl. Has anyone used it yet? I usually use Valvoline SynPower. According to the container it should last 15,000 miles before you need to change it. Wow, since when would they advertise that on their own product. Saying that could cut profits... Anyway, I'll be monitoring the color of the oil to see how long it takes to turn colors. I won't take it more then 4,500 miles if I can even go that long as my engine is old.

Mobile 1 oil filter as well and off we go ......

I'M REDMAN

[rsiwicki]

hey red....I got the exact same stuff in my car. I think I have about 2,000 miles on this oil change at yes I will be changing at the 4,000~5,000 interval. I don't want to risk 15,000 miles as they say on some claim that would do me no good if my engine blew up because I read the label and believed in their claim. Mine was an extra $0.65 per bottle and so I was like WTF....might as well buy the longer lasting stuff even though I will not be going past 5,000 miles. When I last checked....at 2,000 miles it was a somewhat light carmel color.

I wonder if for that extra you might as well go Royal Purple? I tried to put Royal in at Peninsula Infiniti on Monday but the mechanic did read the service writers request to use my oil in the truck and when i got home I found 6 quarts of the Royal sitting there.

I just ran Redline for my last crank case and now Quaker State Dyno juice, not sure I could tell the difference driving it...

[Falkdesigns]

Amsoil and Redline are both better than Royal Purple. Both cost ~7.50 a qt. and Amsoil filters for the Q are 14.00. They're the only oils I use in the Q, and I prefer Amsoil over any other. I've been doing extended OCI's on my cars for 5+ years now, I'm a true believer, but I only put about 8-9 k on the oil with a filter change half way through.

[BadQ45t]

Okay, I have no data to go off to say they are better, but I saw good reviews off Royal Purple. You think Mobile 1 is better than Royal?

[Falkdesigns]

Royal Purple is good, but it's not the best. Not sure how it stacks up against Mobil 1. Amsoil has the edge because they were the very first in Synthetics, since 1972. There is a relatively new test, API Sequence IIIF. Amsoil 10-30 was run 3 times longer than any other oil tested (80 hours of continuous running in a high temperature setting) and STILL beat all other competitors hands down. At the end of the 80 hours, the engine is torn down and inspected (a 1996 Buick 3800 series II V6) and: "Even at three times the standard Sequence IIIF test length, the oil pan, screen and valves showed no signs of deposits, oxidation or plugging. By keeping engines clean and deposit-free, AMSOIL Motor Oils effectively reduce wear and keep engines running smoothly for extended drain intervals."

My car's free Redline diet (oops, did I say free :O ) will be over in about 3 months and she'll be back on her Amsoil diet at my full expense. I don't mind paying for what I know to be the best oil, not what I think, what I know.

[1993TanJ30]

Amsoil is definately the shiznit!

[qship96]

there are a handful of top teir synthetic oils that one could argue as being the best- amsoil,redline,motul,synergyn come to mind- the one thing that turns me off on amsoil is their tupperware/mary kay/ amway approach to marketing-pyramid like,with propaganda being shoved down resellers throats,and many in-house "tests" claiming their superiority over all other brands-yet a look at independant oil analysis results shows that of these 4 oils,each does extremely well.

[Falkdesigns]

All of Amsoil's tests are independently done, such as the one I posted above. I don't know what you're talking about regarding tupperware stuff. I get mine from my mechanic, and you can buy it at Super Autobacs, don't you ever wonder why Mobil 1 never show Amsoil in thier tests??? I sure as hell know why.

edit: You know what sold me on Amsoil in the first place? Racing Beat, the Mazda tuners/racers. They raced and won thier class in the 24 hours of Daytona back in the 80's in a first gen RX-7, they hold land speed records in RX-7's, and hold many other win's in racing. They swear by the stuff, and have used it over 25 years and still swear by it. That's not Amsoil pushing thier product, that's an independant company with 110% confidence in a product. They could sell anything, but they don't, they only sell Amsoil and they only use Amsoil (I used to have an RX-7, so I had lot's of Racing Beat products). Honda's factory dirt bike team use it (Kevin Windham), and on Honda dirt bike commercials the Amsoil logo is bigger on the jersey's than the Honda logo!!

I have always been interested in trying Amsoil, but have not found a local place to buy them from. So, anybody know a place in the SF Bay Area (preferably in San Jose)?

[Jesda]

The Amsoil v. Mobil 1 v. [X Brand] debate never ends, and its a good thing. I love the competition! Royal Purple, however, is apparently a very poor value for money.

I happily settle for the Supertech brand.

For you folks who are into the old fashioned stuff, Schucks/Checker/Kraegen has Chevron Supreme on sale for 89 cents! Fred says its pretty good among dino oils in its class.

[FarFetched]

What about Kendall oils?

[maxnix]

What about Kendall oils?

It's mentioned in the oil threads.

I use Royal Purple in my differential as it is 75W-140 synthetic, good for TX summers and low capacity differentials.

[Jesda]

I have one objection to Amsoil...

I cant buy it at the same place I buy my filters:Wal-Mart, OReilly, Schucks, Advance, Autozone

So they lose out on my business. I tend to do oil changes frequently and on a whim (during a 2700-3400 mile period), so I like to pick up supplies nearby and for cheap. In the spring and fall I sometimes even run a synthetic blend for 2500 miles.

[PalmerWMD]

What about Kendall oils?

Used to be among the best Dinos. Now its made elsewhere (still in US tho)Not bad not stellar I <do> like their 5w-40 synthetic Kendall tho.Meets some very tough requirements

Fred..

[QUOTE=Falkdesigns]Royal Purple is good, but it's not the best. Not sure how it stacks up against Mobil 1.

I gotta think that Royal is better, from everything I've read it is as good as Redline...just cheaper. Bottom line all Syns are good. I put it into my Z replacing Redline and cannot see any diff (but really can you tell the diff with oil very often?

Here's a previous post from Fred about RP:

1) Actually they never reall let anyone know what their base stock is but from MSDS its not that also keep in mind that group 5 is very spendy ( think Redline) and they couldt make RP at this price if it was group5 RP sell at a group 4 pricepoint. Even so I suspect they are not even group 4 as their website would be sure to brag about it ( like Mobil and AMSOIL) but they dont.THis leads me to blieve they are group 3 tops, possibly group 2+ and/or a blend2)You can meet some prettyy tpough requiremtn with a good Blend Valvoline Durablend 10w-40 meets even the toughest ACEA A3 req's, which are more demanding than any API spec so far.3)Absolutely4)Tru albeit the examples mentioned arent real good as their spread is close. a good comparison would be a 5w-40 syn vs a 10w-40 vonventional the conventional will have a lot of thickeners the syn very very few.5) SYnpowr inb a 40 weight makes 5w-40 are you sure this isnt it? no 10w-40 last time I checked ( some months ago)6)Yes it does whichmeans it sacrificed API certification in the interest of better protection under hard use

[BadQ45t]

Okay, sort of greek to me, I have only bought it once but heard it was pretty good stuff. either way better than Dyno juice. So consensus is buy Mobile 1 or Redline??

[Jesda]

...or amsoil.

[Falkdesigns]

Amsoil is THE best though. People can have opinions on this, but I have NEVER seen an oil comparison chart with ANY oil topping Amsoil. In fact, I challenge someone to find one! Amsoil is on top of every comparison chart I've seen, unless it's simply left out (why would X brand show a chart with Amsoil over thier product?).

[Jesda]

I would doubt the quality of Amsoil. They just need to get their butts in gear and expand distribution!

Edit: I meant to say "wouldn't"

You would?? I'm pretty sure you meant Would'nt

[BadQ45t]

Never even seen Amsoil on the shelf, where do you buy it?

[maxnix]

Mutli Level Marketing type distribution. You also can become a distributor.

The best oil is fresh oil - no contaminants. Synthetics will perform better cold and not break down as easily hot. The crank case does not know what kind of oil it has, so it has to be changed when contaminated or broken down, regardless. All the synthetics are superior to the conventional counterparts in performance over a wider range of operating conditions.

Keep it fresh and you will be fine, even with conventional.

[Falkdesigns]

The garage I use stocks it and all the filters, Arrow Automotive on Rosecrans, near LAX. Super Autobacs in Stanton also stock it, as well as Redline, Royal Purple and Motul.

[BadQ45t]

Yet another reason to miss LA....but than again the smog, traffic and crime, I'll stay in Half Moon Bay and rough it.

I agree, fresh oil is the best oil...I'll have to hit Arrow up sometime when I'm in town for a change!

[texasoil]

Lube Oil quality is always a hotly debated topic. Kendall is part of Quaker-State part of Pennzoil--a well known -make it as cheap as possible and advertise the hell out of it' outfit. Amsoil IS a QUALITY based product and IS great. However, with regular 3-4K changes (good filter too)on Valvoline, Chevron Dello, Havoline, Fire&Ice, one will never experience a lube oil caused wear or deposit problem in their engine. Note that Mobil-1 IS NOT the best product. Another extremely important part of the solution is good gasoline--one with a high detergency (one of the top teir or 'drive clean' ) fuels. Putting the 'ultra long change interval' oil in and then changing every 4-5K is throwing money away in buckets. Either you believe the stuff is worth the extra $$ because you don't have to change it as often--or you don't. It does not provide any superior anti-wear or anti-corrosion protection over the other oils mentioned in those 4-5K miles--but they WILL maintain a very high level of detergency and anti-oxidation performance much longer. A modern engine running good fuel and filters, on the highway, can very safely run these 'long-life' oils 15K miles between changes. Me--I change every 3-4 K using the 'conventional' oils mentioned because it gives me a chance to take a look underneath, ensures crankcase dilution never happens, ensures any trace coolant leak is spotted , ensured great engine protection, and is most cost effective. Oil is cheap, hard parts are expensive. 90% of us do not follow a driving cycle that best fits the 'long-life' oil forte.

[elwesso]

Right now, im running redline 10w30 and its starting to make me feel iffy, im going to replace it soon, its getting dark but not too dark.... ive had it in there about 3 months, or like 3500 miles or something.... I dont remember... Either way, ill probably just go to something like durablend or something.. Still for $30/case for M1 syn, that seems hard to beat and you WILL have protection for that 4000 miles. In my case, I prefer to run the synthetic because I take a lot of short trips and that is really hard on the oil. It may go close to a week before the oil gets to full operating temp!...

Anyway, I still think the filter is more important than the oil.... Id say that most good oils by reputable companies will be fine at 4000 miles, synthetic or not synthetic.... Im glad I have about 8 60u00 filters in my garage!
