Hi,

Anyone know what is the best oil to use for the LX570 ?
i use 5W-30 but i am not sure if it is the best for my country condition:
i am actually located in CAMBODIA so the weather is really hot.

some people advice on 0W20 or 0W30 but isnt it for Cold country?

any suggestion or advice is really appreciated.

Thanks

 

how can no one know what they r putting into their engine lol

anyone ?????

 

sorry this is late. haven't been checkin these forums out. i do my own changes (1x) so far. the owner's manual recommends 0w20, if not available, then 5w20.

 

0W-20 and 0W-30 oils are thinner so running them in sok khmai should be all good bro. You a government official to be driving an LX?

 

 

Is the engine oil in the LX-570 conventional or synthetic? Just bought my 2010 and could not find it in the manaul

 

no matter where you at, just use Synthetic oil is best, I think since you are in Combodia is such a hot tempature country just as same as Vietnam, the conventional oil would burn quick and slug in the engine which no good, I all way go with synthetic no matter what

 

According to my local dealership, the standard oil put into the LX570 is synthetic blend.

 

the owners manual states 5w30 from freezing temp to 100 degress and up

 

1) I would ONLY follow what is written in the Owner manual
2) For summer I would recommend the 5-20W
3) For winter I would recommend the 0-20W

Does anyone know the difference? When the Oil is HOT, there is no difference between the two above. The spec on the cars manual on the high end is 20W, isn’t that correct? Then do not exceed that. Even for the folks that live in Qatar or very HOT climents, do not exceed the 20W mark period. Follow the manual ONLY not what the local dealer tells you. The new Lexus engines are made with a lot more precision given the advance technologies in machining these days therefore the engine tolerances and seals used at the time of design they designed the engine with the 0-20W and 5-20W.....Please make no exceptions. Going higher 30W or 40W is a thicker oil and as moving parts are moving with tight tolerances, its hard for the thicker oil to properly lubricate in tight spots. Also its more pressure on seals as thicker oil has a higher level of resistance. Think of a shock absorber: thinker oil moves it slower and lighter oil moves the shock faster due to less pressure build up.
Now as far as the lower number of 0 vs 5. This impacts the cold starts. Both are excellent but the 0 will lubricate the engine more and oil will move easier faster thru out the engine at cold starts but once the engine warms up, both are the same.

So again for very cold climents use the 0-20W for hot use the 5-20W. for in-between you can alternate winter vs summer.

Now as far as brand, that is personal taste. I would use Mobil 1 only. Please note there is a difference between Mobil 1 vs Mobil super synthetic. Both are great but the Mobil 1 has more additives and hence more expensive. The Mobil 1 has been used for a long long time and I would not go cheap on an LX570. Stick to the Mobil 1. The Super is a cheaper version of Mobil 1 and does not have all the protection that Mobil 1 has. Many of the Toyota dealers and Lexus dealers went cheap to improve the margins and now have the Mobil super synthetic instead of Mobil 1. You have an LX and this is a 80K SUV. USE Mobil 1 and use only original factory filter. Do not use substitutes. period. that’s my two cents.
