I used the search function to find discussions about oil preferences and experience. Not ONE entry would come up under multiple search attempts. Is the search function just plain stupid, or is it possible we haven't discussed oil choices?

 

This topic has been discussed ad-nauseam on most other car forums...it is discouraged here.

 

Oooookaaaaaay....

 

Don't know why it's programmed this way, but the forum search function ignores any word of three characters or less. So if you search for "oil," you will not have any results. You CAN, however, put the word "oil" in a phrase, in quotes, and get results. For instance, search for "oil filter" and you'll come up with plenty.

That being said, WhiteXKR has a point. None of us learn much from the same regurgitation of opinions on oil. Now if someone has something really NEW to say, then...

 

Makes sense. I was just contemplating changing my oil from Mobil One HM to another since it is now 10-40 and I think I really should be using the 5-30. I also have 5 Qts of M1 EP 5-30 on hand that I could use, but with the low miles I put on the car (< 3K/yr) it doesn't make much sense to me. I also have a remaining 3 Qts in a jug of Penzoil Platinum 5-30 that i could easily grab another jug of. I guess there's really not much difference for the gentle/occasional driving I do. I just like good protection while cruising at 75 or more when heading up through Nevada.

Yeah, I'm a regular visitor there, but it has become a serious hodgepodge of opinions by self-proclaimed "experts" who spend half their lives analyzing their oil ever few thousand miles and trying to sell the Amsoil products.

I tried to get some info on the M1 "Truck & SUV" 5w-30 to see if it was acceptable for our Jags but the search function wouldn't separate it from all the other M1 stuff and thousands of posts about everything from M1 to Castrol to PP to Amsoil....etc. IMO the T&SUV M1 is probably for heavy duty, but low RPM use. But what the heck do I know.

 

I hear ya. That's precisely why we don't need to replicate all of those discussions over here on THIS forum.

 

If you really want to review it all....you can search "*oil*"

Put me down as being strongly in favor of oil...

 

The place is littered with the carcasses of dead horses waiting for another beating by the armchair quarterbacks.

Oil is okay stuff though. Add coolant, sparkplugs and atf to the list too.

 

Octane? Anybody for an octane thrash?

Of more importance why does this bunny have a pancake on his head?

 

The Jaguar XK manuals from 1996-2006 just state to use 5w-30 motor oil if I recall correctly. Use of fossil or synthetic is not mentioned.

Use whatever brand makes you feel happy inside. Enjoy your fake peace of mind.

As long as you perform routine maintenance at regular intervals it doesn't matter what you use.

 

Not sure what you mean by "fake peace of mind", but when Jag recommended only changing the oil once a year or 10,000 miles long before we had extended life synthetics I have to question their sanity and reasoning (especially during the nikasil years). The only way I'd do that in mine would be to use EP oil and change the filter at least once in the duration.

Time is more my "enemy" than miles these days.

 

There's no evidence that a 10K interval is inappropriate either on dino or synthetic oil, so maybe their reasoning wasn't so far off.............

 

Sorry, you sound a bit confused... What does pre or post-Nikasil have anything to do with oil change intervals?

By 'fake piece of mind', I'm saying that whatever oil and whatever interval you feel comfortable with, as opposed to doing whatever anyone else tells you. If you aren't comfortable driving 5k miles after an oil change before servicing it again, drop it down to 3k miles. Or if you're comfortable going longer.... whatever. Same goes with synthetic. If you think it'll help your car run better, you'll feel better regardless if it's a fact or not. Mostly unsubstantiated placebo effect.

BTW, if you have an engine with Nikasil coated liners right now that's running fine, you're actually better off than someone with the newer engines without the lining.

You seemed to have missed this part. I'll repost to emphasize my point:

Because, no matter what oil you use, if you're changing it on a regular interval, you'll be changing it long before it breaks down and can cause any harm.

 

Part of my dillema is being caused by the fact that when I bought the car it had about 106K on it, and the oil was a beautiful golden color and very clean. I thought the P.O. had just changed it, but as I got into further maintenance I came to doubt that. Still, the oil remained clean looking for quite a few miles...until I finally changed it at 111,500K. Even then it still looked pretty good, but this was now 14 months later.

I went with the Mobil 1 HM 10-40 because I live in a hot climate. The only filter I could get at the time was a Fram PH5618 -- not even one of their premium filters. While that filter cost about double the others they market, I have my doubts about it's real quality. As you know, the choice of high quality filters for our cars is somewhat limited.

Anyway, I'm going with the Bosch 72-whatever, and I've already replaced the Fram with it regardless of whether or not I change the rest of the oil. So, now I need to decide whether to get another Qt. or two of the M1-HM and just keep using it for another 1500-2500 miles.........or, just dump it all and start over with a 5-30 of high quality (M1, PP, Edge, or some other).

If the M1 in my crankcase looked as clean as the oil that was in it when I bought it there would be no question about continuing longer (especially with the filter change). But I am puzzled a little by the darkening of the M1 and its appearance of being "dirty".

So, there I am.

 

I think your 'dilemma' is partially self induced by using oil colour as a meaningful reference or indicator.

 

I've realized the problem. You read far too much marketing literature from oil companies and far too much hyperbole on the internet.

Get the cheapest oil you can find and change it every 3-5k miles. You, nor the car, will notice any difference whatsoever.

 

Mikey - I literally LOL I swear I did.......

To the OP - Please discuss "oil" as much as you wish, you may get some takers here, you may not as its kinda been done to death...lol

Personally, for my point of view....I love the stuff and always keep some in my car

 

Yer both proberly right.
