I seem to burn oil constantly in my truck, iv got a 1994 toyota pickup 4x4 22re i4 and wondering if anyone knew why?

How many miles and what is the history of the truck?

140,000 and im second owner, just put a new oil filter w/ oil change, new engine bolts for valve cover, thats bout the history for it

With that low of miles, you should not be burning oil.
How much is it drinking? 1quart per XXX miles?

Any leaks? Any buildup on the plugs?

i havent seen any leaks that i know of yet, just some around the oil filter but that was always there, made sure that was on their tighter than a ticks a$$ but i did check the plugs yet though.

you might want to consider getting new rings for the pistons. If the oil ring is going bad, then that would be a reason that you are burning oil. Espically with over 100,000 miles, if you havent done a rebuild then you might want to consider it.

Oil burning should not be an issue till at least 200k. 140k is way too soon unless something went wrong. Check your plugs for buildup.

It should say on the outside of the container if you can mix synth. with mineral, however I have heard that you must not mix the two. Regards Fintan

It doesn't even say if it's 5w50,10w40 or whatever, must read it later Alistair burgess J

Engine Oil (4A-FE engine) - Castrol Magnatec, nothing else on the market even comes close. It doesn't have to be the high spec synthetic, but if you can afford it then use the sythethic. viscosity rating will depend slightly upon where you live - for instance if you live in siberia you'll want at best a 5W-30. If you live in britain a 10W-30 or 10W-40 would be the just the job.
trans axle oil - again, a high spec synthic if you can affford it - GL5, 75W-90.
filters - whatever comes off the shelf. no real difference between makes.
plugs - not sure, I've not had much luck with finding anything other than standard ones from an independant autoparts shop.

cheap ngk coppers do for plugs. trans axle oil - have a look at redline, i hear good things about it. filters - blueprint ot proper toyota.
