'00 LS400 Cruise control

[Moe47]

Yep, plays FLAC straight off. Off topic, Mohammed, what oil do you use for the LS? have you had any luck finding Mobil1 in this country? Been looking everywhere to try the 10W-30 and can't find it for the life of me.

[M.Yasir]

Oil... i am using normal shell engine oil 15W 50...

[Moe47]

Wow, I would have thought that's a little too thick? What does your owner's manual say? 

[M.Yasir]

apparently the manual which i downloaded from this forum for 98-2000 LS 400 says 5W 30..

[Moe47]

Yeah, but I think now that the cars have run in the hundreds of thousands and the fact that we live in a natural oven here, 5W30 would be too thin. You might be right on using the 15W50, But then I might be speaking out my behind. It would be nice if the gurus here could clear this up for us though!

I had sent Mobil US an enquiry and this is the reply I got: 

"Moe,

Your inquiry has reached the Mobil help desk for US market oils in US market vehicles. I know that here, we would be recommending a 5W-30 rather than a 10W-30 for your Lexus. Typically, when dealing with hot environments, that second number on a multi-viscosity oil is the primary concern. 

Whether 5W-30 or 10W-30, once the engine is up to operating temperature, they're both being measured as a 30.  The main difference between the two will be the flow characteristics during a cold start first thing in the morning. A 5W is going to flow faster than a 10W, so your bearings and valve train which have been draining oil over night will receive a new coat of oil faster with a 5W.

I will be happy to refer your original question to our UAE desk for recommendations on locally available products.

EDIT: received another email from Exxon Egypt as Exxon US forwarded my issue to the middle east. Here's what it says.
