So the same can be said with RP and syn oils then right?
If it was right out of the bottle, even an oil company research lab would have a difficult time saying for sure dino or syn, but once it gets some carbon, gasoline, engine gunk and wear metals in it - fugetaboutit. (Unless it comes out of the sump still purple....DOH!) S |
Y'all sure are getting in a huffy about something that doesn't matter...
The owner's manual says the REQUIRED service level of oil to be used is API Service SL. The RECOMMENDED viscosity rating is 5W-20. In lawyer speak, that means as long as the oil you use is API Service SL, REGARDLESS of the viscosity rating, Mazda will honor the warranty. If the viscosity rating were a strict number to be adhered to, it would not be RECOMMENDED, it would be REQUIRED. It says this in two different places... Referring to my 2004 model, page 8-9 of the owner's manual: Recommended Oil Oil container labels provide important information. [image showing the API Service SL seal with SAE 5W-20 oil and "Energy Conserving words] The quality designation SL or ILSAC must be on the label Again on page 10-5, in the Lubricant Quality table, viscosity is NOT listed, only the Classification (API Service SL). For RECOMMENDED SAE viscosity numbers, see page 8-9. What's that all mean? It means you can use whatever viscosity level oil you want, provided that oil meets the appropriate temperature ranges for where you live. AKA, somebody that lives in Alaska and uses 20W-50 is going to have a hard case of proving engine failure wasn't caused by their extremely thick oil that's not rated for cold temperature. Likewise, someone in Arizona would have a hard time if they use 0W-15 in the summertime, 'cause it's not rated for those temperatures... But 10W-40, 5W-30, 5W-20 are all three MID-TEMPERATURE range oils, and there's not a chance in hell Mazda (or any other car manufacturer) can deny warranty coverage based on you using it. They can't deny warranty coverage based on their RECOMMENDATION, only their REQUIREMENTS. See how that works? |
5W-20 has been fine for me here.
I can see going with 5W-30 or even -40 in much warmer southern climes however. Regular oil changes (3k in my practice) are as much/more important than the viscosity rating. 40k isn't allot of miles and shouldn't be driving your decision. Pre-mix 4 oz per tank if you track/autocross allot just to be safe.

im wonding if there is any one around the new england are that can help me decide what oil i should use i used 5 20 but now i got 40k and im wondering if i should change over if any one has some advice let me know thank
|
I use 10w40 now and I used to use 5w30, I say it straight to their face. (stealership)
Go ahead and try to void my warranty, see what happens. Guess what, they tried to void my engine warranty back then, nothing happens. SUCK IT BITCH. To OP : hahah, you should've speak with the owner of the stealership, tell him to stop paying minimum wage to the service adviser's position. |
^OP: click links in nycpgs's sig - it has some good info

Because those damn regional guys are always " OMG" about specific things..but if the warranty and all only RECOMMENDS..doesn't say REQUIRED..then guess what. They can go F themselves. |
100k on 5w-30 in the winter 10w-30 in the summer.

Funny (not really), they supply the car with a winter type oil and summer only tires.:banghead:

The '06 Chapter 10 table doesn't even list the API stuff...it just refers to the "recommended" oil viscosity. But there are a couple of places that refer to the "specified" oil. Which brings us to another aspect of lawyerspeak...it's designed so that it always needs further interpretation, usually involving billable time. ;) Ken |
^lol. billable hour blood suckers . . .
I'm not going to quote it, but I agree that Frontier's post is 100% brilliant. Dead on. Good job, and such.

FYI, there is NO way a dealer could take a used oil sample and have an analysis determine the difference between 5w20 and, say, 10w40. No way, trust me I work in a refinery and do oil tests all day, and it just ain't that precise, there is so much overlap that a 30 could be also called a 40 etc, and once the oil has been in the car and sheared, diluted, heated and depleted - all bets are off. . . . If a guy had a new '8 under warranty and kept receipt of buying an RX-8 filter and a jug of 5w20 regularly, who would know if he put 10w40 in, and used the 5w20 in the wifes mini-van?

The mazda dealership doesn't have ANY method by which to test what kind of oil is in your motor. Now, even if they did it would be difficult to tell what your oil began as because of how oil breaks down as it's used. As time goes on the additive package degrades and the viscosity changes. . . . Stealth beat me to it! There is no way they will know what you run unless you tell them. If some stealership/MNAO ever actually tried to say they tested the oil & it wasn't to spec, any lawyer would smile quietly and lick their chops.

I'll have to double check my receipts, but I'm pretty sure the jug-o-oil at Walmart scans as motor oil, includes the brand name, container size (maybe?) and NO MENTION at all of weight. He did beat you to it, but kudos to both of you. lol There is no way they will know what you run unless you tell them.

Let me just say that in the summer, if I drive to OC or LA I've noticed that the oil light will come on while driving on the freeway even if the oil level isn't low. That was using 5-20 Mobil One. I suspect switching to 5-30 would solve that.

what dealer? and what was the clerks name?

i suspect you have the original oil pan which had this issue. If you had the upgraded oil pan with better baffling this wouldn't occur. what you experience has nothing to do with the oil grade you are using.

Dealer here refused to use 10W30 in mine so I bounced.

and You expect "these" people to know how to add some 2 stroke oil every couple tanks of gas ? Thats why. |
I use the engine light as my guide, has worked just fine for the last 60k including track days. Usually when the light comes on I add half a quart and its full. Even with the light on its not below the bottom mark on the dipstick. I still check it every other fillup or so but using the oil light is fine. I read the owners manual.

screw all this oil stuff, just premix the gas with some 50-50 and call it a day.....there......apex seal is happy
.......jk lol....i just saw the post above mine referencing that :) beat me to the shot...... |
Hey guys, sorry, but prolly a noob question... What's the difference between all these different types of oils? 5W-20, 5W-30, 10W-40, etc?
I know Mazda recommends the 5W-20. I just recently bought a used 2004 RX-8 with 47,000 miles. The previous owned got all his oil changes at the Mazda dealership and adds 5W-20 when needed. Should I continue to use the 5W-20? If not, why should I switch, what are the benefits? |
