rotella 10w -30

[BillyP]

Ben,

5w-40 is fine for southern or northern climates or any other climate you'll find in between. In all reality, a good 15w-40 is all you need in LA. In other words, either one would be fine for you. The 15w-40 might be a little easier to find. Wal-Mart carries either one though.

Ok. This was actually in reference to the RotellaT Synthetic thread below, but no one has replied to it.

My oil spec graph for my Toyota shows 5w30 is ok up to 50 degrees F, and I was debating whether or not it was ok for my climate. (South Louisiana) I am running Rotella Synthetic in other engines at the house, and was starting to get concerned when I saw that graph.

If I understand correctly, if you have a 5w40 oil, its 5w when cold and 40w when warm? Or is that backwards?

I know that Rotella Synthetic does not have the friction modifiers found in "energy conserving" oils, but it would be nice to keep less varieties of oils around the house. I bet I have 6 different kinds of oils at home, but not enough to do an oil change on anything. /w3tcompact/icons/smile.gif

ROTELLA® T Synthetic
Product benefits and technology
Shell ROTELLA® T Synthetic 5W-40 is a fully synthetic, heavy-duty engine oil. It combines outstanding cold-temperature starting and advanced soot-handling capacity. It helps prolong engine life, even in extreme conditions. The proprietary Shell formulation meets virtually every advanced OEM specification. Because it uses the Shell synthetic base oil technology, ROTELLA® T Synthetic is more fluid than conventional oils under cold start conditions, which means better circulation, less wear on start-up, and easier starting throughout the service period, with little to no viscosity breakdown. Because it carries the Shell and ROTELLA® names, you can count on high standards and quality.

Superb soot handling
Stricter emission requirements and engine design changes have led to more soot going into the oil in today’s high-technology diesel engines. Rotella® T Synthetic provides excellent protection against engine wear and viscosity thickening due to soot.

ROTELLA® T Synthetic:

Meets engine warranty requirements to the maximum allowable drain by the OEM
Provides outstanding wear protection
Withstands extreme heat
Provides superb soot handling
Enhances cold-temperature starting
Has low volatility
Offers superior oxidation stability
Improves fuel economy, up to 3%
Lowers oil consumption
Is available where you buy ROTELLA® T
Applications
Because ROTELLA® T Synthetic 5W-40 was developed especially to meet the requirements of today’s high performance diesel engines and because it carries the latest gasoline engine credentials (API SL), it’s ideally suited for use in heavy-duty and light-duty diesel and gasoline engines, even in the most extreme conditions.

Specifications and approvals
ROTELLA® T Synthetic 5W-40 meets or exceeds all requirements of API CH-4, CG-4, CF-4, and CF; Cummins CES 20076 (extended drain); Mack EO-M Plus (extended drain); Caterpillar, Detroit Diesel, Dodge, Ford, International, Navistar and Volvo.

I too read that on the Rotella site, but no where on there does it say what temps its good for.

I was able to dig up a pdf file from the RotellaT site that had the info I was looking for.

They even have forums for motorcycles, and compact tractors, along with Shell reps that answer questions.

I don't know what kind of Toyota you have. I have a 2000 Camry, and it calls for 5w30 for all time from less than -20 to over 100F. It is the prefered oil, for all use. I don't know of any oil that says not over 50F. For the 30 is for the high temp. and it is good for real high temp. Are you sure you didn't look at Centigrade, for 38 C is the same as 100F. Just trying to figure out what you are meaning. For syntheic, should be alright for hotter temps than other oils.

I have 4 Toyotas and all but the diesel have the same oil selection <A target="_blank" HREF=http://members.cox.net/toyota904/toyota%20oil.jpg>chart.</A>
It does not specifically say not to use 5w30, nor do I think it will be a problem, but what do you read from the chart?

 

[pruntyc]

I have never seen a chart like the one you posted. But I do know if you can run 10W30 at a given high temp, you can also run the 5W30 at the same temp. As its the last number that tells you how hot you can use it. The first number is how low a temp to use it. The oil don't really change that much, from cold to hot, the multi just lets you use a oil that would be way too thin if it were a straight weight. Like 10W would get super thin at high temps. But the multi, lets you have the best of both worlds, low temp starts and high temp protection. So I think what they are trying to tell you is to use the 5W30 at low temps. other wise maybe you should use 10W30 or 10W40. My oil filler cap has 5W30 as the prefered oil wrote right on it.

Ben, we are getting a bit off track talking about Toyota's and tractors but I took a look at your attachment and the Toyota Oil Specification chart... your Toyota's, at least the manual you have copied must be 1993 or older... The SG oil classification is the latest one noted in the attachment and that rating was for 1993 and older cars... we have gone through SH (1996), SJ (1998) and are now on GF-3 - SL (2001) API Classifications...GF-4 gasoline oils will be out in 2004... Remember, at least so far, almost all oils have been backward compatible, so you can use the latest oils with older engines.. It is entirely possible that as the oil specifications have changed going forward, the temperature range has also expanded since the SG Rating in your chart... For example, most of my cars specify the 5W30 weight up to 85 - 90 degrees in ambient temperature.. then specify 10W30 or 20W50 in higher temp ranges...

In any event these are Gasoline engine oils we are talking about, not Diesel "C" rated oils.. latest being CI that just came out... most diesel oils still meet the last classification CH and older ratings which fits still most diesel engines being manufactered... Discussing gasoline oils is not bi-lateral... you cannot use gasoline oils in diesels but you can use diesel oil in gasoline, that's why most diesel oils carry both the C & the S ratings...

http://www.howstuffworks.com/question164.htm If you will go to this web site, it will explain it better than I can. Both for gas cars and diesel tractors. Just follow all the threads to get all the information, and I think it will answer all the questions about oil, that you may have. That is why we get on here, is to learn and try to help others.
