Earliest oil change ever - and now having second thoughts (1 Viewer)

Interesting idea about the Moly add

Those are not my ideas. I was infected with them from this website, Bob Is The Oil Guy where there are twice as many opinions as there are participants, similar to the GX 550 Forum. Though, one can learn a lot from them.*

FYI - I also changed my oil early, at 500 miles, but I included 1/2 bottle (150 ml) of Liqui Moly additive to retain the higher level of molybdenum and then changed again at 5000 miles with the other 1/2 bottle of Liqui Moly. I'm currently at 9,000 miles and the next oil change I'll start using straight synthetic engine oil. Using too much Liqui Moly, such as using 2 entire bottles (600 ml) or more in one oil change, is where filter problems reportedly begin.

*Some important things I learned from BITOG website are oils are grouped in categories I, II, III, IV, V in order of lowest to highest quality or uniformity of oil molecules. Synthetic oil is considered superior since it has a greater uniformity of carbon chains than does naturally sourced oil, and this high uniformity translates to vastly superior levels of engine protection by withstanding heat and retaining lubrication longer.
Also, here in the US it is legal to brand engine oil as "full synthetic" even when it is derived from non-synthetic or hydrocracked natural oil (Groups I, II, III, thus significantly lower quality and lesser uniformity oil). This is done to identify an oil as not being a blend of natural and synthetic oils. In Europe, however, engine oils labeled as "synthetic" must be fully derived from the highest uniformity oils, such as Group IV (PAO), Group V (Ester), or Group GTL (natural gas to liquid) sources. There are a few brands that market and sell authentic fully-synthetic oils here in the US, including:
Amsoil Signature Series
Motul 8100 and 300V series
Royal Purple
Liqui Moly - a German brand that adheres to the EU definition of "synthetic" oil using NG to Liquid process.
Pennzoil Ultra Premium - one flavor of US oil that reportedly uses only NG to forge this line of synthetic oil
Mobil 1 Extended Performance - most of the Mobil 1 lines are "synthetics" derived from lowest uniformity Groups I to III based oil, and thusly are not true "full synthetic" oil, but Extended Performance line reportedly meets the EU definition.

@Emergencymed

Let me know what you put together, as I'd be interested in a GX/LC Crawl. Maybe on the dunes? Or do you have some tougher terrain in mind?

I wonder where the Toyota/Lexus oil falls on this scale

I wonder where the Toyota/Lexus oil falls on this scale

ExxonMobile makes the Toyota "full synthetic" oil in North America, but I don't know what group of oil is used, because, in general, Mobil 1 uses the "synthetic" loop hole in marketing and could make synthetic oil from grades I, II, and III. However, Toyota does have strict specifications that include additives such as extra molybdenum so Toyota may also require truly full synthetic oil from grades IV, V and GTL. In the EU Castrol produces oil for Toyota, thus if branded "synthetic" that oil must be produced from grades IV, V or GTL petroleum sources per EU requirements.
