Is it o.k. to use synthetic oil in my 2002 camry?

any 20w-30 grade will suffice you can use mineral oil , a mix of mineral and synthetic or straight synthetic
don;t mix your own but buy the special duel oil
Personally I use mineral oil and change it every 10k as that removes all of the contaminants out of the engine , and cheaper too

They make a high mileage motor oil. Also you need to consider whether or not it is using oil. IF you have not used synthetic and it is not using oil, you can continue using what you are using.

Not for normal driving, a good quality oil grade SN or better is fine. If you drive hard, tow a lot, or drive in very dusty, hot or cold climates, a synthetic oil eg Castro Edge, is a good idea.

if you use a synthetic blend oil yes, don't mix regular with synthetic yourself

You could try changing the oil and using synthetic, maybe a lighter flavor like 0-30w for a while but you will likely need to have the cam sprocket replaced. Toyota has issued a service bulletin relating to this problem, it involves an oil pressure activated variable cam timing sprocket that gets stuck in the wrong position. Some people have had success getting their dealers to pay for this but I wouldn't count on it by any means.

The car takes 5w-30 semi synthetic oil. However, if you have never put synthetic oil in the car I would recommend using regular oil. I would also advise you check with your local jaguar dealer. The reason for this is if your car is not use to that kind of oil from day one it could cause seal leaks.

This specification has been updated from 5W-30 to include
5W-20 per a Technical Service Bulletin from the
manufacturer. 5W-20 is the preferred recommendation.

If you are using synthetic oil, keep using synthetic.....same as above in synthetic form.

5 qts of 5w-30.

I personally prefer MOBIL1 brand ..You can decide as per your wish..


SOME ADDITIONAL INFORMATION:

There are many grades of oil weights whichever you want to call it. Heres how it works
Oils main job is to keep the engine clean, lubed, running cool ect. The grade usually 5w20 5w30 or 10w30 ect. Theres many of them as well which can be consfusing at times. Oil weight is measure by cold and hot . For ex: 5w30 The 5 weight is when the oil is cold and 30 is the weight when its hot. The reason being is the the less the weight when its cold the easier the oil can get to the top of the engine and lube it to prevent cold engine damage. Once its heated up its a 30 weight and is thick enough to protect your engine.( most engine damage is caused when the engine is cold )You should use the proper grade that your engine calls for. Being toyota its probably 5 or 10w 30.If you live up north i would recommenda 5w30 weight.You can easily find out which grade you should use by your owners manual or under the hood on the oil cap. However there are synthetic oils as well. Synthetic oils have man made additives to help the engine run cooler, the oil is naturally slicker to help it move around easier and boost performance of the engine resulting in better mpgas well. They have alot of additives to prevent engine wear ect. One good thing about a synthetic oil is you can go longer on the oil change. Instead of the normal 3,000 miles oil change you can go 4 or 5 k. Theres also synthetic blends. Which are good too but youll have to read about it more to decide for yourself what you think you need. Synthetic oils are better for someone who travels alot or puts extreme conditions on an engine such as idling for long periods of time stop and go traffic its really good for anything to be honest.. I would recommend using synthetic if you decide to keep the car for a while. It has many benefits.

They say you can, but remember, not a good idea to switch back if you change your mind later. Personally I'd go with 5w30 for winter then maybe 10w30 or 10w40 for summer. All kinds of arguments for and against synthetic, vs standard. personally I prefer standard & change at proper intervals.

Your check oil light correct? if oil level is full then you have a bad oil level sensor
