Synthetic oil
#3
Lead Lap
I have a 2013 350 and after the free oil change I plan to use 5W20 regular oil. The engine in the Lexus is the same as my 2006 Avalon that used 5W20 which was recommended by Toyota.

there was a long thread on toyota spec oil. reportedly its composition is specified by the factory.
and there is a difference. how much and what does it really mean, I don't really know.
I would only use a full synthetic, but kinda doubt it would make any difference which brand.

Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

Like most owners I wish to use an oil to give me good economy, cold weather performance AND the best engine protection. I've been using a 5-30 synthetic in my 07ES which has always been parked outside in the North NJ winters since 2006 and never had a starting issue in the cold. So I wonder if continuing to use a 5-30 rather than a 0-20 in my newly acquired 14ES might be best for engine wear, even if I am giving up a little in fuel economy. I wonder also whether using 5-30 would void the warranty. Finally, having not yet taken possession of the 14ES I am wondering whether Lexus for the sake of decreasing car weight has decreased the battery size (resulting also in a decrease in output) since an 0-20 engine would be slightly easier to turn over in the cold than a 5-30 engine.

It might impact FE very slightly but I don't see how it would impact warranty since in some respects your giving better protection. 10-20 actually scares me a little in a hot environment like here in south tx. I need to check the manual for specs according to driving conditions to get ready for summer. Suggest you check too.

All the specs in the manual says is that a higher viscosity may be called for in cases of higher speeds or heavy loads. I still plan on asking the dealer about our local conditions. Summer here in stop and go traffic is brutal. I do know that the Toyota dealership used 5-30 dino in my 2007 Camry Hybrid and it is essentially the same engine.
