Poll - LX570 owners using regular 87 octane or Premium

[TeCKis300]

I think we are in complete agreement about using the appropriate grade fuel, to summarize and address the OP... incorrect fuel grade and insufficient octane rating can reduce performance and potentially subject the engine to damage.

In later posts it seemed that others were advocating the use of higher grade/octane fuel to increase performance/mileage on engines designed to operate on lower grade fuels .... that was the intent of the Engine Master posts to show that in a specific objective test (anecdotes are subjective tests) no improvement was noted. I believe that in my 200 I would get no advantage to running premium all the time. That being said .... it is possible that in a situation like you describe that I could see LESS performance degradation by running 91 octane but not truly an increase hp and mileage. I guess it really is semantics but in summation the best I can achieve with 91 is just normal performance in a worse case situation ( and yes that is a good thing)

Copy. For the LC, I would just run what's required - 87. There will be limited advantage to running more octane. That said, in extreme cases, there has shown to be some benefits. Too many variables to say if a stock rig on stock tires, towing a milder load could see the same.

DIY Smartphone Scan Gauge - OBD Fusion

Apologies if this has been answered, but which of the OBD monitors would you recommend if price is not a priority. I’m an iPhone user and like data and relative ease of use. I’m using iPhone with VeePeak OBDCheck BLE Bluetooth scanner ($34) and OBD Fusion App ($10) for iOS, with Toyota codes...

5W30 is recommended RoTW in 3UR. In fact. All the way up to 15W40 is spec’d.

in a UAE manual, 20w50

I would not go that thick unless it is hot outside. Unless you are in the southwest, 20w50 I think will have no positive gains, other than wear resistance. I have thought about 10w40 or 15w40, synthetic oil.

Well you would be a candidate then for sure.

One really good, cheap 15w40 synthetic, is Supertech.

It seems that the 3URFE can accommodate 0w20-20w50, depending on climate, according to non US manuals.

15w40 has a good mix of cold flow at start and HTHS, probably the worlds most proven multigrade

appreciate the help

i will grab some15w40 supertech

Just a reminder - not ALL multigrade oils between 0W-20 and 20W-50 are recommended by Toyota. Here's the chart most folks reference:

There are only six recommended oils:

0W-20
5W-20
5W-30
10W-30
15W-40
20W-50

Personally, I have no problem with any of these six based on use case; but I would caution against choosing a multigrade that is NOT on this list of six. For example, 5W-40 is NOT recommended even though it does fall within the overall range.

Just my US$0.02.

It all has to do with application and viscosity. The second number is its flow characteristics at operating temps. Notice, that 20-50 are noted. Also the most common modern viscosities are listed. 5w50, 0w40, 10w40, and 5w40, all of which neatly fall in between the viscosity ranges in both 40c and 100c temps. I SUSPECT they just did not see the value in listing those two as they are not as common, at least in 2008, I am not sure that 0w40 even existed in 2008.

As long as the oil falls within the viscosity range, respective to the ambient temp, all is good. In this case 20w is minimum, and 50wt is maximum. 5w40 dual rated C\S diesel oil or 0w40 M1 FS would be a great choice, in higher temps like in Death Valley.

0w40 and 10w30, seems like the middle of the road, correct viscosity, high HTHS numbers and low NOACK numbers, a very durable blend.

In Death Valley and like places like Las Vegas and Phoenix, summer temps are an average of above 100 everyday. With these ambient temps a thicker grade would be suitable, with a lower pumpability for "cold" morning starts. 5w40 would be a great choice.

Also, none of those viscosity grades are listed in the US manual. Only 0 and 5w20, neither of which I would ever run in Death Valley.

The only knock against running 0w40/5w40 would be higher acquisition cost per quart and how much VI was added to achieve said spec.

Below, are three examples, same price.......

What spec are you referring to? I know of no spec, beyond ACEA or API certifications that the 3URFE require. Is there one?

All of which can be had today at any walmart in the country. Just using M1 for example.

Supertech 15w40 synthetic diesel oil is actually cheaper per quart than the ones above, it is in a gallon jug as opposed to 5 quarts.

That rationale makes no sense. 0W30 is also in the range and several members run that.

Thank you for the links. '

The spec/grade of oil meeting sae j300 criteria. The m1 euro full saps 0w40 version you posted also meet oe/other organization validation spec like Porsches own C40.

 

[skrypj]

I ran Pennzoil Platinum Euro 0W-40 my last oil change. I wanna say I bought 20 quarts for something like $37 with a rebate from Pennzoil so I had some extra laying around
