What type of oil do you use in your Protege...?

[Longboy]

What brand of oil do you use in your Protege? I use Castrol GTX High Mileage in my 93' protege LX.

Redline or Motul.

I run penzoil conventional in my 01 with 165k miles. It burns synthetic for some reason. With older cars you should run conventional or high mileage and you shouldnt use synthetic or so I've been told. I'm not quite sure why though

Red Line 5W-30.

The oil I use is part synthetic, but if I shouldn't be running synthetic (even just part synthetic), Perhaps I should change oils if at all possible. If I were to change oil from part synthetic to regular (so to speak) oil, do I have to do anything to make the change over simple, and not mess anything up?

[tweety2300]

Just do a normal oil change, don't believe anything you hear about not being able to mix conventional and synthetic oil. If you couldn't then how can they make synthetic blend?

I see absolutely no reason why you shouldn't use fully synthetic oil in older or high mileage engines that have seen regularly scheduled oil changes with either mineral or synthetic oil. If you like the synthetic blend you're using, continue with it. I suggest however that you switch to a full synthetic formulation because this will ensure peak performance and maximum engine longevity. For more information about synthetic oils, go to:

Well say for instance, if i was to change to a full synthetic oil in my protege, and i didn't like it for whatever odd reason, are there any issues when changing back over to a conventional oil? I heard that once you change from conventional to synthetic...its an act of congress to change back to a "normal" oil. Is this true? I forgot what brand but i did run full synthetic in my old 92' Nissan Sentra without issues. I switched the sentra's oil over while the engine had over 300,000 miles on it. I wouldn't mind trying it in the mazda. It also has well over 300,000 miles on it, and is running a part synthetic blend. Ill give full synthetic a shot, seeing as how i am nearing the oil change period. I just want to make sure that it wont be a pain...or cause any issues...should i was to go back to what im using now....or even go back a "normal" oil.

What you "heard" about changing from conventional to synthetic oil and then having a problem changing back to conventional oil is a total myth.

Synthetic engine oils and mineral oils are completely compatible and can be mixed together although it's not good practice because doing so weakens and reduces the benefits of the synthetic portion. So, once you change to synthetic oil, changing back to mineral oil (or a blend) is easy and will cause no damage or problems of any kind. And no, the engine doesn't have to be flushed after a changeover - another myth.

Considering the benefits of synthetic oil in terms of performance, increased oil change intervals, decreased fuel consumption, and increased engine longevity (including cleaner internals) why, except for the increased price, would you consider using anything but synthetic in this day and age?

When I use conventional/Dino/ mineral/ whatever else you want to call it I burn a qt ever 1000-1500 miles. Synthetic on the other hand I go through a qt every 500-800 miles. Although the previous owner ran the car into the ground and never did any maintenance to it so it has bad valve seals and piston rings are show signs of starting to go. That may be why but in my case it's just better to use conventional

Could be possible Tweety. In got my Mazda from my uncle, who was fairly anal about keeping the Mazda running well. Even with well over 300,000 miles on it, it still runs like a champ. Hell, it got me to California and back with no issues what so ever. Ill give the synthetic a shot, should i be able to afford it.

I use Castrol Syntec 5W-40 and now I'm trying out Amsoil 5W-40.

[Longboy]

Ive never heard of Amsoil or Redline or anything like that. Where are these brands available?
