No, oil is tested in all conditions If you have a manual It may tell a different weight of oil but I kind of doubt it. If you have a turbo car the I wold use synthetic oil personally due to the heat that is given at a turbo especially when shut down as there is no oil pressure there.

i have corolla model 95 using carburetor with 1.3L engine size. My problem, when I pull out the engine oil stick to see the oil level while the engine is on, the engine oil bubbles out from the engine oil stick tube. What could be the problem? Sir, please give me helpful advice because I really don't have any idea in car problems, I will wait from your reply before I will go to car mechanic. Thanks a lot for your kind help

You may have overfilled the crankcase. Always check oil level with engine off on a level surface.

If oil is discolored (chocolate, milky color) you may have a bad head gasket.

You think they should use some additive to reduce oil consumption. My car consumes about 1 liter for every 2000 miles.

I think it's not overfilled because when the oil change shop did the oil change, he always used to check and I too saw that he filled it exactly. Connecting to my car problems which is bubbling engine oil, also I heard little knocking noise inside the engine although it's not constant knocking. Please help me identify the problem before I went to mechanic to avoid wasting more money in buying unnecessary parts which could not fix the problem.
Thanks a lot for your kind held and wishing that you can give me more positive and identical response to my car problem as soon as possible.

No additives of any kind I've never seen them work in my opinion and with the miles on your engine that is considered normal consumption.

Have the oil pressure checked with a mechanical gauge. The oil bypass in the pump may not be working. The pump type that Toyota uses can create a lot of pressure.

You would consider it an exaggerated consumption for a motor with high mileage.

I follow your advice that it may be overfilled in oil. So I went back to oil shop and took a check-up because as I observed in the morning before I start my engine that the oil was overlap in the dipstick maximum or in the full measurement.
Now, the oil was reduce to its exact measurement but still the blow-by of oil was there. Do you think this cause my engine or some internal parts of my engine went bad? Please give me advice.

Thanks a lot for always giving your time in replying to our problems

Make sure the PCV valve is working, if clogged it will cause excessive internal pressure.

Next step, if problem perists, is to check compression on all cylinders.

Engine Performance problem
1992 Toyota Corolla 4 cyl Front Wheel Drive Manual

hi I live in the tropics where temperature is around 30 degrees.
My car consumes oil so I use oil treatment and high mileage oil. Can I use monograde oil SAE 40. Do I need to add oil treatment with it. Or should I continue my high mileage with oil treatment.

Assumng you mean 30C, then a straight weight is fine.

You most likely have bad valve stem seals.

All oils have to pass oil manufacturing standards, so any brand would be fine.
