Show must go on!
So, I'm succumbing to peer pressure, ads, youtubers and fancy packaging:
Decided that my next oil change going to be Amsoil 0W-20 synthetic.
Previously my '11 AWD only seen LGMO/Exxon 0W-20 XS formula oil and OCI is every 6000km (well, before me it was low grade 5W-40 which ruined both heads and I replaced those. since then - LGMO only).
My engine does not consume a drop of oil and is currently at about 80k miles on odo.
Amsoil and most other US oils are not readily available in our parts, but I was quite pleased that Amsoil was in stock locally and not much pricier than LGMO (guilty, getting that at laughable 10usd per 1L in drums).

What can I expect? If anything? That's a pure experiment for me, please understand the hesitation. I have no engine problems at this moment and it pulls like a mother trucker.

 

What is so special about Amsoil?

 

Its insanely good at everything except cost and availability. Everything they make is a true group 4 synthetic and consistently the best period. I use their stuff for everything other than engine oil due to cost and annoyance, only exceptions are the advanced trans since I'm still not willing to risk my 8 speeds. It noticeably reduces drag in winter in diffs etc

 

Thank you! I never used any of their products. It indeed seems to be hard to find.

 

It's $223 for an oil filter and 10 litres of oil in Canada, too rich for my blood. Pennzoil ultra and an oem filter is under $100.

 

It does seem to be too expensive, maybe if I had a new LC500, I would consider Amsoil. Otherwise, it is just a "good-to-know".

 

It's just I vaguely recollect switching from tgmo to Idemitsu brand oil in my LS430 with plenty of miles. But I do remember engine becoming at least little bit quieter.
So, biting the bullet (Amsoil) approx. next month when oil change time comes. And yes, as Gerf said, it's going to cost me about 200 USD.

 

The only thing I run their oil in is my 03 truck, nothing else is worth it to me due to the insane cost despite it being very very good.

 

Amsoil 0w-20 as well as the Amsoil oil filter. I had sent my oil in for an analysis to Blackstone labs at different intervals (5K,10K, and 15K) . Oil was still great at 15K.

 

What were your iron and nickel levels at 10k and 15k?

 

5k
Iron 7
Nickel 0
10K
Iron 9
Nickel 0
15k
Iron 12
Nickel 0

 

thank you for tested results, ordered a kit from amzoil. $172 shipped to California, will change my OCI to 15k and test at 15k.

 

My bus conversion has a detroit diesel 8v71 and takes about 7 GALLONS of straight 40wt oil (getting hard to find) and can see running a test. But on my 12 ls460 I just use Kirkland 0w20 every 5-7k miles only costing me about $50 in parts including OEM filter. At 250k+ miles does not lose/burn a drop and is pretty darn clean. Will take a picture at next change.

my m11 Cummins in our motorhome with its shallower aluminum pan takes 9 gallons. Deeper pan is 11 gallons.

wife is Ill. No time to change things that often. 15 to 20k miles a year users. 15k or more OCI or 1 year will help on time

 

FYI, I use a local shop in sf, give them filter and oil and they will change out for $20 in no time. An independent gas station shop, not one of those chain shops and ez to confirm they changed everything right.
I was amazed the the 460 took 2 gallons of oil, but it's got nothing on the truck engines! Hope your wife pulls through.
