Oil Change

I have a 15 GL550 with 67K miles. I'm looking to change the oil myself for the first time on the GL and I'm looking for recommendations on the type of oil I should use.

I live in South Florida and temps are normally between high 80's F and low 90's F. The GL currently has 0W-40 but I'm thinking on switching to 5w-40 or maybe 10w-40 since I live in a very warm temperature were snow is never a factor.

What are you guys using on warm climates?

I appreciate any feed back, thanks!

I used Mobil 1 European Car Formula 0w-40 when I lived in NJ. Now I'm in Charlotte, North Carolina and use Castrol Edge Euro A3/B4 European Advanced Full Synthetic 5w-30 - it's on the list of approved oils for this engine.

I used Mobil 1 European Car Formula 0w-40 and still had scored cylinders so I do not know what to recommend. I believe the oil is good oil.

Go for 10w40, will have higher pressure, plus it is too warn in FL for 0w40 for the most of the year around. Normally it is recommended to use Mobil 1 European Cars oil.
