Just wanted to know what oils you guys run for an IS350??

Who is the resident expert on oil and frequents BobIsTheOilGuy forum???

I guess Mobil 1 5W30 is fine if changing every 5K - 8K. But wanted know if something might be better without the extra cost. If it was like $15-20 more per oil change, I might consider it.

Thanks.

 

I just started using Royal Purple and have noticed that my car runs smoother.

 

Mobil 1 + lucas pure synthetic is what i use

 

regarding this oil...I've read that the new models now run 0w-20 rather than the traditional 5W-30. I guess they do it for better MPG. What do you guys think of running 0W-30? on an 08 IS250?

 

I think the new ones use 5W-20

 

My '06 IS350 originally came with 5-30, but there was soon a TSB instructing the dealers to switch to 5-20 in this car. I have owned the car for almost two years, and have run Mobil 1 5-20 Synthetic since I've had it. I use Purolator filters, btw. But you can usually score the factory Toyota filters pretty cheap from Sewell. I am curious about the Royal Purple, as I have heard a lot about it. It is only about a dollar a quart more than the Mobil 1 if you buy it by the quart, but I get the 5 quart jug of Mobil 1 from Walmart for about $26, which is by far cheaper than anyone else....

 

Sure ya do...

 

Keep in mind I just switched from conventional oil to synthetic. I know people say they dont think RP is better but I have no problem spending a few extra bucks for oil. Only the best for my baby

 

Can't go wrong with German Castrol 0W-30. A lot of FI guys run this oil.

 

Yes. My 2011 uses 0W-20 and I'm assuming 2011+ use it as well.

 

I use Mobil 1 synthetic 5W-30 and a WIX filter every 10,000 miles

 

Anyone have a link / copy of the TSB that says to switch to 5-20 for this car? Is this switch even for older 2007 IS350???

What's better for protection? 20 or 30?? I don't care about gas mileage. It's not going to make that much of difference for me. Rather save the engine and keep the car till 150K+ than more ware and tear for a gas savings.

thanks.

 

07 is350 using 0w20 for 5 years now. no issues. in so cali

 

It was 2006 only. 07-10 still run 5W30


No reason to run a WIX filter, OEM filters are cheap and what the car was designed with

 

i've always used oem filters, and 5w30 mobil 1. I consider mobil 1 to be really good products, and I've noticed the difference switching from castrol blends that the dealer used to throw in my car. mobil 1 is high quality stuff, i'd recommend spending the extra few $$ on this, and I personally think that's good enough. these forums are full of people who live and swear by mobil 1, so i'd recommend using that personally.

I use it in my 1997 honda accord these days even, with 150,xxx miles. it's just awesome stuff.

09 250.
