Pros and Cons for 0w-x0 oil.
Those who have used 0w-x0 oils (preferrably Mobil 1), can you summarise the pros and cons you have discovered during the usage. If any problems, what did you replace it with?
Thanks.
Thanks.

If you use a 0W-x0 oil, you can expect better start ups (especially in cold weather) and even in warm weather smoother smarts. When driving the accelerator shouldn't feel heavy, but rather quite smooth. However, I would stick to a 0W20 to 0W40. 0W40 for a Mobil 1 was my favorite among the grades I had tried in my RX (0W40, 5W50, 15W50, 10W30, 5W30).
Issues can occur on older vehicles above 100,000 miles where something like a 0W20 or 0W30 (unless it is the German Castrol 0W30 that can feel like a W40 when warmed up) can get chewed up (sheared) by an older engine. If you race your vehicle, a 0W40 would also be preferable in a newer vehicle as the oil can also get sheared as well (take it from someone who knows).

I have been hearing great things about that Amsoil 0W20...should it become to hard to get the German Castrol (it already is), I want to give Amsoil a shot (but no Amsoil in Mexico)

I am using 0w-50 ENEOS by Nippo Oil, the best JDM oil I guess.
Pros:
Shorter time to warm up the car, and I feel it gives me more soild (faster response time) when pressing on the gas paddle. This could be a mind effect only.
Cons:
Cost more gas since higher oil weight. I say it runs 30 miles less when compare with regular 20/30 oils.
According to the Eneos, I should see a significant of lowering in temperature also but I never check. I don't drive my wife's is350 much... but I am enjoying using the best and JDM only.

Anyways, is Amsoil available in local stores by any chance?
I've only heard good things about it.

You can ask dealer if they will let you watch them put the oil in, but then you have to be there.

I have never seen Amsoil in stores in the U.S., though some specialty auto places sometimes stock it. Actually, on a recent trip to Jamaica, the parts store that sold me my Harrier emblem did have it available.

Does Lexus ***** about the oil if it's not the type of oil mentioned in the TSB(5W-20)?

Part of the reason for this was that Mobil did not readily sell the W30 or W40 in Mexico City and I had a very, very, very difficult time trying to get anything in a W30 or W40 without blowing my paycheck (it was special order). Toyota was using a regular 5W30 which I didn't want to use. In the past 3 years, this has changed 180 degrees and now lower weight oils are plentiful.

Do NOT use a 50 weight oil in your Toyota. You could damage the engine. The first number rating is for start-up and cold weather. "0w", the w is a designation for winter. The other number is for an engine running at operating temp. The problem with using 50 weight oil is the actual size of the molecules. In 50 weight oil the molecules may be too big to get in the very close bearing tolerances. Do yourself a favor and get that oil out of your engine and use only the recommended weight. This is NOT a case of "Bigger is Better"!
