why could my 95 Toyota Camry be knocking?

may baby

Yesterday I drove my car and it started trembling and/or knocking low so i put w 10-30 oil in it....I drove for about 30 min to get home as I was driving the knocking and trembling wasn't as bad ...it was based off of how I switched gears...If i switched them to early I'd hear a sound and it would start back but if i switched gears slower i wouldn't hear the sound and the trembling wouldn't be as bad....Is my engine going out?????? or did i just need oil?































p/s I brought the car from my uncle back in June his kids drove back and fourth to school everyday on the freeway he said it got a oil change so I haven't put any in since.















ps it has over 200,ooo miles

You're the one dumping oil in the motor and you are asking us if the motor needs oil??? Didn't you check the level on the dipstick before adding more oil?















P/S Better learn a few things about a car or you will be walking! Mechanical things need maintaining!

to add,















*if* it is an engine knock, the ones we fear, crank, rod, wrist pin, when they first show up, if something hasn't just let go, the engine *typically* runs w/o missing or stumbling. that's *typically*. not always the case.































if it is the feared knock, your description, *comes and goes while shifting*, smacks of a load bearing component. rod main or wrist pin. associated symptom w/this issue is slow to build oil pressure after starting. that is the oil light is slow to go out after start.































however, many other things can sound like a "knock" to the untrained ear. take it in to a reputable shop. any mechanic worth their salt can tell a rod, crank, even wrist pin and valve train issues just standing next to it.















there are minor things like pcv valve clogged and rocker noises that can easily cause stumbling and to the untrained ear, sound like a knock.

on a used vehicle, inspection of oil and coolant levels, and fluid leaks under the vehicle, are most critical, and should be done b4 driving every time till one gains confidence in the vehicle. slacking up these inspections till the point that recommended service intervals are met.
