oil to use in 2015 IS 350 f sport 29,000 miles?

 

sorry for stealing OP's thread but i have the same question. i have an IS200T. i was thinking of using 0w-20 on the winter and 5w30 on summer. what do you think? or should i do opposite?

 

Use the oil your car manual recommends. I don't see a valid reason to experiment with something else.

 

yep. use full synthetic 0w-20. as far a brand goes? whatever makes you happy. i use royal purple

 

Mobil 1 full synthetic. Walmart sells 5 qrt for less than $30! Gotta get two more individual quarts tho. =)

 

I too just purchased 0w20 mobil one fr Walmart along with 2 add qts. I m about to hit 30k and I'm going the same route

 

Motul over here...

 

you can find mobil 1 or pennzoil ultra oil on rebate too

 

Toyota Genuine Motor Oil 0W-20

 

+1 for motul

 

Mobil 1 Synthetic 0W-20. Perfect for the 3IS

 

I use whatever 0W20 full synthetic Walmart has on sale. I'm not brand loyal and have been swapping oil brands damn near every oil change since I drove a 1991 Acura Integra, hasn't hurt anything and my wallet thanks me.

 

startup is where most engine wear happens, good synthetic can help mitigate this since synthetic flows a lot better during colder temps than conventional oil. So it will get to lubricating faster and earlier

 

Mobil 1 is good stuff but some cars don't like it (Subies), I personally use either Toyota Genuine oil, Motul or Amsoil for my vehicles. All have done right by me so far.

 

isn't the oil that lexus uses mobil 1? i thought that that was mentioned when i last took my car in for an oil change, although i could be wrong. when i had my 2IS, i used to bring my own oil (royal purple) to the dealership and have them use that, but i was told that i was wasting my money if i didn't track the car (and i didn't).
