Sup all? Hey---is Castrol (5w-30, or something?) "high milage" oil worth trying on a '92 Teg GS w/~142k miles? Just wanted some opinions on this. Thanx!! > Sup all? Hey---is Castrol (5w-30, or something?) "high milage" oil worth > trying on a '92 Teg GS w/~142k miles? Just wanted some opinions on this. > Thanx!! I would like to know that as well. Are high mileage oils simply a gimmick or has anyone seen true difference ? My initial reaction to your question is that if your engine "purrs", i.e.. runs well, does not burn oil , has great compression, etc... the regular "mineral" car oil works as well (the term "mineral" is in reference to the typical oil we buy at any car part store, as opposed to synthetic oil). I read a 2001 review of the major oil products in CR and they found no benefit between the most and least expensive oils. Their key suggestion is whatever oil you have, change it frequently (every 5000k). Of course, I have been biased towards synthetic oil as I live in a very cold region (Ottawa). I did the experiment for my kid's school project :-) of leaving a litre of "normal" Castrol 5w-30 oil outside one night at -20c and one bottle of Castrol synthetic oil. After 12 hours outside, the "normal" oil poured into a boll like molasses, and took 90 second(-ish) of vigorous mixing with a spoon at room temperature to regain normal fluidity. I hate to think what it does to the engine when we start in the morning! The synthetic oil was as fluid and smooth as if it had been inside all night. I know this does not answer your question, but I felt like adding my very limited knowledge of oil to this collective knowledge databank called the internet! My 2 cents. > > Sup all? Hey---is Castrol (5w-30, or something?) "high milage" > oil worth [quoted text clipped - 30 lines] > > My 2 cents. Ahhhhh--the normal seems to not like the cold cery much. Were the 2 varieties you tested (synth. vs. mineral) the same weight (5w30)? I'm in just noth of Dallas, Texas, so the cold weather isn't an issue. I've tried the synthetic (Purple Pony) or something like that quite a while ago. I don't recall why I did that, I guess just to try something new. I liked the idea of not having to change the oil untill 5k miles or so, & if I was to keep using the synthetic ("high performance"?) oil, I was told that I need only change the filter every other 5k miles. As "good" as that sounds, I just dont like the idea of going over 3k miles until the next oil change, personally. See, we're now only talking about synth. blends vs. mineral ("normal") oil. We still havn't hit the advantages of "high mileage" oils vs. normal mineral oils and synthetics.

Thanx for replying, Ice. Yes they were both the same weight. With synthetic oils, I would still change the filter with the oil even if you can keep these a little longer. I have not tried this test with semi-synthetic so perhaps this is a good compromised. However a colleague noted that the semi-synthetic actually does little to be more fluid then mineral oils as the later "emprison" the synthetic oils molecule when the temp falls. However, you are right that we are digressing! I am still interested in others' opinion about these high mileage oils as well, so I will keep checking back this tread... >>Sup all? Hey---is Castrol (5w-30, or something?) "high milage" > [quoted text clipped - 34 lines] > > My 2 cents. I did the same sort of thing, but with Mobil 1 and just put it in the deep freeze. The stuff ran smooth, but I don't believe it was as cold as -20 Let's see if I have this right... Ice Cube's yard is colder than Franz's deep freeze? Hmm. Ottawa is a nice place to visit but I'm glad I live in Florida. I just sold my 14 year old Maxima. I have used Mobil 1 synthetic oil in it since it was new. I changed the oil twice a year because I only put about 7,000 miles a year on it. Often, I would go to a Speedy-Lube place for regular oil and filter change. Then, I would go home and drain the new regular oil out of the crank case and replace it with Mobil 1. It was my way of thoroughly flushing out the old oil as some always remains. By doing this, my oil was almost always lite amber to honey colored and free of impurities. The engine always ran at the same temperature. I never had any oil leaks or consumption. In short, the engine actually was performing better at 14 years old than it did when new. In fact, my new Acura TL with a supposed 270 HP and 5 speed AT is only marginally quicker. The Maxima listed 160 HP. Mechanics who checked the Maxima's specs and vital signs said that it had no discernable wear (100k miles). I sold it to my best friend's 17 year old daughter in pristine condition (both). Within six weeks, she totaled it when she rear-ended another car at noon on Saturday. Now I understand why their insurance is so expensive. No, she wasn't hurt which is good because now I'm gonna kill her! (jk) > >>Sup all? Hey---is Castrol (5w-30, or something?)

I used regular Castrol 10-40 in my 89 integra (which I had for 9 years bought it 60k on it and drove it to 170k). I did have the oil changed every 3-5000 miles. I would recommend finding a shop to use regularly for consistency (and preferably one with a good rep). I am from warm weather (actually hot is more problem than cold) climate, and I have not used synthetic in my car, so I cannot comment on that side of things. Keep changing the oil and you should get some good miles out of your '92. I have changed to Valvoline for my '97 that I got a couple of years ago. This was recommended by my Acura dealer (it has a warranty and I have them doing the service for now), and it seems to be fine as well. Posted by Rubber Dino The high mileage oils you're seeing is regular conventional oil, with stop leak additives added to it. The oils do work, but they don't solve every problem. at most they'll simply help rejuvenate seals, maybe stopping a bit of smoking, but nothing beyond that. It wouldn't hurt to use them, however, I find that regular conventional oil and an oil treatment once in a while seems to keep things happy (I use the valvoline synpower oil treatment, I don't burn any oil up to 3300 miles, dunno what else it's doing, as I used to burn a quart every 1500.) > Sup all?
