Toyota recommends 0w20. What is the disadvantage to using 0w30 when towing? 6000lbs trailer and 100 degree weather?

Technically the 0w30 will run a bit hotter and push the oil pressure up a bit. I don't think it will be a problem, but why are you wanting to deviate from the manufacturer recommendation?

The Tundra's 5.7 has an engine oil cooler. Don't be afraid of 0W-20 when towing in warm weather. I would recommend TGMO 0W-20 (Toyota Genuine Motor Oil)

Question:
Any Concerns with Using a 15W-50 Viscosity Motor Oil When Towing a Heavy Load?
I have an '07 Tundra 5.7 I-force. Toyota calls for 0W-20 or 5W-20. My mechanic wants to run 15W-50 since I tow a 7500-lb travel trailer on a monthly basis. I have noticed tapping when the engine is cold when I use 15W-50. Will the heavier weight oil damage the engine?
-- Kevin Edewaard, Tallahassee, FL

Answer:
We recommend that you follow your manufacturer's recommended viscosity grade. The engine has been designed hydraulically to handle the 20 grade oil. It will also provide better low temperature pumping at start-up, allowing oil to get to the top end quicker which may quiet the tapping you hear on start-up.

Thinner oil cools better, the disadvantages of thicker oil could be higher engine temperatures but with an oil cooler should be negligible although possibly measurable.

Google the Penrite Oil Australian site you will see that it promotes the extra w10 so according to the Penrite philosophy running a w-30 in a vehicle designed for a 0w-20 is a standard recommendation in Australia.

BTW check the OEM manual the oil grade recommendations are usually linked to climate.

Also check the Redline Oil Company Australian website you will note that it recommends different grades of oils for various operating conditions and climates eg below 25deg C. and that oil brand claims to use high temperature PAO, ester oils etc for hot operating conditions.

I just figured with the fairly heavy trailer weight and the warm northern California weather, that I would be putting a decent strain on the motor and therefore may need a oil with a higher viscosity? If you guys are telling me no need, then I am fine with running 0w20. I just want to do what's best for the engine.

Toyota recommends 10k oil change intervals with the 0w20. The manual states if you were to use 0w30 that its recommended to change oil at 5000 miles.

They call out that interval specifically for a 0W-30?

I believe the Toyota manuals say that 0w20 is recommended, but that a heavier grade of oil may be used if driving a high speeds or under a heavy load. Read the manual very carefully, but I believe they leave the window open for thicker oils under certain circumstances. Nothing wrong with 0w20, but if I were towing in the heat in a Tundra I'd probably move up to a 0w30 or 5w30 synthetic. Just my opinion.

None. I would be inclined to run a 10w30 synthetic.

Yep, they started doing since XW20 were phased in. Reading between the lines, xW20 are good for most but not all drivers. Surprise, surprise wink
