I'll have to confess... I've rarely used the search engine. Like to get my direct questions answered pronto. But until spike mentioned me doing an engine flush, I never even thought anything of diesel oil. I was content using Castrol GTX high mileage engine oil. The diesel recommendation was kind of out of the blue... And at first I though Spike was kidding me! But sure enough I now fill up with Rotella diesel oil

 

Took me less than a minute to find it. And nowhere did I say I couldn't find it. But why should I spend time looking up useless info when people could just post a link or reference to it?! That's about as stupid as quoting the bible, but not giving a reference.

 

If you adjust timing to a certain extent you can harness the benefits of higher octane fuel, but pretty much only if you adjust for it. If you put 91 in a car meant to run 87 you won't be doing too much harm, maybe clogging some cats, fouling the chambers, and losing power, but it wouldn't be catastrophic. A lot of engines are quite high strung though(see Land Rover), especially modern ones. If you put 87 in a 91 modern car typically it will pull the timing which reduces power. If it doesn't have a knock sensor though, or if it is broken, then it won't notice and you will have detonation. Depending on severity of the detonation you can junk the motor, and you will be running a lot less power.

Why take the risk of detonation....? The engine may seem to run fine, but you have to remember, regardless of compression ratio, the engine management system is programmed to adjust timing for a higher octane fuel. I have yet to see someone market or even claim to have built anything to adjust the timing in a Land Rover.

 

just to keep this theme going... a .0245 second search yeilded this filter option. these are the larger filters available at virtually any store.

K&N 3001 or Mobil 1- 301

The amount of repeat Q's on this site is getting out of hand, I see now why the folks over on Dweb and IH8Mud have gotten the reputation of being A-Holes, it gets old when people don't even attempt to do their own research and instead post repeat questions because it's a "waste of their time" to try a search.

 

right.... I've actually had a couple people get pissed at me and throw attitude my way when I've told them to download rave or search for the info....

"but if you know it then why not just tell me?"

As they say... "teach a man to fish......"

***this is me referencing a bible quote and not telling you where it is from***

 

Relax there nancy. I put j/k for a reason. It was a joke. Not sure how you call it useless information though? You requested it, therefor it's not useless.

 

Retards. I never requested the info. I was trying to teach you that if you have specific questions about info you find, you need to share the reference/source. Most of the time people read crap and then open their mouth only to find out later they were an idiot because they did not continue to read the rest of the info.

Guess you can't teach a new dog old tricks(reference; my Dad)

p.s. Auzzie, the name is Chris, not Nancy. If you can't get that right with the info right in front of your nose, what the hell are you doing with a Land Rover...

 

gosh.. I hope I'm not a retard...


I truly hope thes following words can act as a means to close out this venemous thread.

All NAS Discos are catalyst vehicles from the factory which as we can see from this referenced page 45 would mean you can determine that all NAS discos are 9.35:1 compression.

which means.... RUN at least 91 gas if you are in the U.S.

Now everyone quit bitchin' and get out and go wheelin'.

 

Just to be safe, I'm going to get tested.
