alot of people say use hdeo,s how much better are they then Castrol GTX 10w30 .OR ARE THEY?? does anyone have any stats to support that hdeo,s are better than Castrol GTX 10w30.if anyone can provide stats to compare rotella and other hdeo,s i would love to compare them.can anyone get info from the engine oil evalulator site or other sites so i can compare.this is for auto engines,v8 boat engines, and air cooled motorcycles and garden tractors. thank you for the help.
 
Better? That's completely application dependent. You aren't going to get any stats unless you specify what exactly you are using the engine for. In a marine application an hdeo such as rotella conventional would be far better simply because of sustained high rpms,oil heat and shear.
In a car however an hdeo may be a bit thick depending on engine and manufacturers spec.
You gotta be specific or expect lots off smart a$$ answers if any at all.

"Better" depends on the intended application and use. HDEO's are typically more robust for their intended use and while some have dual ratings for gas, in a modest change interval you will probably not see a difference between the two. Regarding the research you propose why not do the searches yourself and post up your findings?

There is an averaged out survey done by a BMW forum of UOA results for a 5K mile OCI that compares different synthetics and non synthetics including GTX 5/30, but I've not seen one with HDEO's. The results were very interesting as they showed very little difference between full synthetics and conventional oils or between brands.

Dude this is like your 5th post on this subject.
ALL OF THE APPLICATIONS YOU DESCRIBE NEED AN SL TYPE ADD PACK
GTX IS SN
HDEO HAS MORE EP AND AW ADDITIVES FOR SUCH APPLICATIONS
HDEO IS DESIGNED FOR 10K OCIS WITHOUT SHEARING
GTX IS NOT AS SHEAR STABLE OR POTENT
HDEO CAN TAKE MORE HEAT WITHOUT BOILING OFF
HDEO HAS A HIGHER HTHS

If these are not good enough answers you could always

DO A GOOGLE SEARCH ON BOTH OILS AND COMPARE!!!

Why would there be a difference? The difference would happen at extended drain intervals where the better lubricant will keep the engine cleaner. And it isn't like the minute variances in PPM between different lubricants means anything. used oil analysis are not a tool to be used to compare the protection ability of lubricants to one another. They could of course be used to determine how each lubricant held up and monitor for contamination.... which is of course what they were designed to do

Castrol 10w30 GTX is a regular passenger car oil.

Not much better or worse than any other conventional SM/SM grade oil, which is to say weak, i.e. okay for modern passenger car under normal driving conditions and frequent oil change intervals.

Not suitable for harsh environments; air cooled power equipment, marine engines, etc.

However, if you want to run it in anything and everything go ahead.
 
If GTX 10w30 cost the same as Rotella 10w30, for a 3-4k mile oil change in a later model econobox, I would use the GTX. For any type of heavy duty use such as those you mentioned, I would definitely be using the Rotella or another HDEO for the reasons electrolover lists.

You know, the fact that a particular oil brand was used by someone's dad or some key marketing phrase or commercial has an impact on someone, or that's just all they ever used or would consider using, can have a stronger effect on a person than facts and figures, or advice from someone who actually knows what might work better in a specific application. I guess electrolover gave him the answer he needed to hear and now he can finally move on.....
 
If you want to use a HDEO, use Rotella T5 10w30.
Check the used oil analysis forum for results.
What do you want to use?
GTX is nothing special.
There are lots of oils between HDEOs and GTX as well.
What are you looking for?

Whats that vot to do with gtx vs hdeo in a lawnmower?
 
Castrol gtx is the best oil in the whole world. You can use it in every machine you own,and if you drink it you will become superman and be able to fly.

for many of you i appreciate you personal experience,s. for some of you it is only a opinion with absolutly no facts to back up your statement,but it makes for interesting reading.some people do in dept reasearch and others well you know, like to talk. to each his own.

Your original question isn't answerable without an application specified. You chose an oil(gtx) and want us to post data on why an hdeo is better or worse,yet you don't specify an engine to compare nor anything for anyone to go on.
Try being specific. I can show you used oil analysis of rotella in my shared sump bikes but gtx cannot be compared because it can't be used in a shared sump bike because of friction modifiers.
How many guys do a used oil analysis on their lawn mowers. How do we even get to that data point?
You come in here,ask an unanswerable question,then post some garbage about opinions. Come on man. You want data try the search function.
I'm sticking with my original statement.
