Help! Car gurus...my 2005 toyota camry has a rattling noise when starting, thereafter it stops. my mechanic says it's the chain and I need frequent oil change than regular. Please how do I stop this as it's giving me concern. And secondly how do I correct the acceleration as it's not responsive like my acura v6. I guess they say it uses a sensor. It responds 1sec after pressing it, instead of the normal response I'm used to. Is this normal since it uses a sensor?

Devirus2:
It stop immediately after ignition

I use ap viscoe 2000. The oil filter is always changed after every service. Meanwhile it happens only at cold start. Usually in the morning or when the car is left for a long time. But afterwards you don't hear the rattling again.

Just as I thought - you're using the wrong grade of oil! Don't you read your car's Owners Manual?
20W-50 oil is way too thick for a modern engine. It's primarily for much older engines, or later ones that have covered a million miles.
Your engine rattles on startup because the oil is too thick, and so does not circulate quick enough, your hydraulic tappets don't pressurise quick enough, and your VVT-I will struggle to work with that heavy oil. Toyota recommend 5W-20 or 5W-30. That glue you're running in your engine will kill it, with the camshafts being the first components to fail.
You don't state what oil filter is used on your engine during an oil change.

My car recommended 5w30, but I've searched for it everywhere and can't find it. The closest I found is 5w40. Can I use it?

Siena:


Sounds like a worn timing chain tensioner, or it could be you're using the wrong grade of engine oil.

What oil do you use? Is the oil filter replaced at EVERY oil change, or "washed" and refitted? Is the oil filter an OEM Toyota item?

Siena:


downgrade to an older car that will tolerate Palm oil.

Rattles can be annoying, and very misleading to their location. It sounds like they changed a motor mount, but look around at all of your suspension, it could be the bushings, a loose bolt, a broken hanger for exhaust to name a few things.

why do you keep lifting responses from Google without referencing the link you stole it from passing yourself as an expert when all you do is Google and shamelessly copy and paste without credit to the real author.

All your posts are stolen verbatim down to the full stop from Google. you are not even smart enough to edit it a little.

Where in Nigeria are you because i have seen 5w30 in Nigeria in synthetic form, though some report they have seen it in dyno form ( I haven't).

Let me share my experience with you, I used to use Visco 2000 which seems a lot better than Mobil XHP which eventually completed the destruction of my engine.

My manual says use 5w30, i drove to Lagos with Visco 2000 and decided to do an oil change before coming back ( I didnt find Visco 2000) so I used Mobil XHP, the day after I arrived, indeed the very the next morning when I started the car, the timing chains started rattling.

One thing led to another including 3 engine rebuilds, but after everything I lost that engine, since then its synthetic for me, initially i did 0w40, then i moved to 5w40 and now I am on 5w30 and while I have covered many many more miles since then and driven the car very hard even redlining it a couple of times, I have had no more chain rattling.
5W30? Mobil or Total? Where can I get one in Lagos pls?
