First post- new to club lexus...

So I just purchased a new 1996 Lexus LS400 with 113,000 miles. the car is in good clean condition and was serviced regularly however I noticed the oil could be changed. I am considering using full synthetic mobile1 5 W- 30 oil but I'm not exactly sure what the previous owner had used. would I be doing any harm by adding full synthetic on an older vehicle or should I use conventional oil in at this point? Should I go heavier possibly 10 -W 30?

Welcome. Synthetic oil is fine, but stick with 5W30.

it's not 'fine' it's all that should be used lol

and the manual does say 10W is ok as long as the car won't be in especially cold temperatures but 5W should be good still

Do not use 10W-__

Use 0W-30 synthetic.

Peruse this post for reasons why;

all you will get here are a bunch of "opinions" , and that is ok, your main question was will you hurt it by changing types: NO! just change it to keep it clean, it dont wear out!!
use what you want, follow your manual... they knew what to write.. and NO I have not read the "book" from Yah.......... but I owned 3 Gulf and 2 Texaco stations before I opened my Automotive shop (30 years)... now at 85, I just pass along common sense... when I can..

First gig as a pump jockey at Standard Oil.

Except for Mercedes, mostly U.S. made vehicles.

Checking oil was part of the service...many needed oil...often a quart.

My LS400 uses no oil...except when I wipe the rag to check it.
