My wife's 2015 toyota corolla, with 1.8litre engine, variable cam timing. The specification for oil basically says, "does it say engine oil on the container?, then you can use that"
Anything from 0-30 to 20-50. And toyotas have a good reputation for longevity.

My brother has a D1 that has done just under 400 000Km,he has had it since it was one year old,does all the work on it himself.Quote:

I always use the specified oil in my vehicles,including the work fleet,and have never ever had an engine issue,manyndoing over 300 000Km.
I think many over think what oil to use,if there are no engine issues,just use the manufacturer specified oil,and if it isn’t available use something that is close.
FWIW,the LC 1VD is specified 0w/30,but some particularly in the tropics use the Penrite HPR 5 5W-40.
Whether the HP5 is beneficial to the longevity of the engine,no one probably knows,it’s all just guesswork.

for what its worth - I've been using Penrite HPR 5w-40 in my TD5 defender for last 9 years and its well into the 800,000 KMs now on original motor

Christian on LR Time does his research and makes sure he is well informed. He explained why he went to the 5W40 with the necessary ACEA codes. It is not unusual to have to increase the viscosity of engine oils on engines that have the wear consistent with higher mileages.
You just have to take the information provided and pay your money and take your chances.
Good luck, I’d stick with Christian’s advice.
The thing is you could go 5w60 . won't help an old engine.. You need to up the first number as it's the operating temp.. HPR5 is basically 15-30 not 5-40. Which is great.. Good start up oil viscosity, good running viscosity.. I used to run Castrol oils, loved them and had access to the "professional" range, on paper with my eyes.. Penrite is better, Mobil, shell etc all have their offerings. Can't say I looked
Sorry Josh, but your statement there is incorrect. The first *w number is related to the oil cold pumpability of the oil (the W stands for winter), the second number is the SAE hot (100deg) viscosity rating so that is what relates to operating temp viscosities not the first numberQuote:

Engine lubricants are classified using the Society of Automotive Engineers (SAE) J300 oil viscosity classification system. Multi-grade engine lubricants, such as SAE 5W-30 or 10W-30, must meet both low temperature and high temperature viscosity requirements. In a SAE 5W-30 engine lubricant:
- “5W” refers to low-temperature viscosity (the "W" denotes winter) and is an indication of how easily the lubricant will flow in cold start-up conditions. At a given temperature a 5W lubricant has a lower viscosity than a 10W lubricant so flows faster during critical start-up. This is sometimes referred to as cold cranking simulator (CCS) viscosity.
- “30” refers to the high temperature viscosity at 100°C, therefore replicating an engines operating temperature.
This is known as an oils kinematic viscosity (KV)—the time it takes for a fixed volume of lubricant to flow through a tube under the force of gravity.
HTHS measures the viscosity (resistance to flow) of an engine lubricant at elevated temperatures under constant shear, simulating the narrow tolerances and high speeds between moving parts in a hot engine.
High Temperature High Shear HTHS viscosity measures the viscosity of an engine lubricant at 150°C and simulates the narrow tolerances and high speeds between moving parts in a hot engine. In particular bearings, the camshaft, the piston rings and liner.
The HTHS viscosity of engine oils is important for the ACEA classification.
- Classes A1, A5 and B1, B5 require an HTHS value of 2.9 to max. ...
- The classes A2, A3, B2, B3 as well as E2, E3, E4 and E5 require an HTHS value of over 3.5 mPas (normal HTHS viscosity).
- For classes C1 and C2, HTHS values ≥ 2.9 are required.
What Christian was pointing out - is read your owners manual and make up your mind with all the information in hand - dont nessecarily trust oil manufactures oil selection charts
Scrounging for numbers, the 5w-40 Enviro+ I use has a hths of 3.6 and HPR5 is 4.0.
Now none of my vehicles have a DPF I might move to the HPR 5.
