While I have faith in AI to some extent, I am still sceptical of its recommendations for the best summertime oil to use on my 2002 Range Rover HSE.
A list of things that an AI said I needed to replace my oil:The sentence is completing itself.
1) Ignore the LR part number and use a 14 mm aluminium crush washer instead.
2-Gallon Reservoir of Shell Rotella T6 15W-40 Full Synthetic Grease
1. Oil Filter Replacement for WIX XP or Mobil 1 Filters M1-301A (Due to its high-efficiency media, silicone anti-drainback valve, and bigger capacity)
1-Brake Cleaner Bottle
Is there a precedent for this?
On the other hand, how can I use better oil to stay cool in the summer?
It is appreciated.

In the midst of getting my oil changed, I just had a brief inquiry.

If you have the answers in the handbook, there's no need to ask AI.

Updating to a new crush washer—copper or aluminum—is highly recommended.
The chart shows that it varies on local weather conditions, however I've been using Castrol 10W-60 ever since my engine was repaired 260,000 miles ago. An oil change requires 5.8 litres.
True to form, the Wix filter works for a variety of US-based vehicles, however it fails to cross-reference the LR part number ERR3340. Mahle OC261 is my go-to.
Unless you're dealing with a major oil leak, there's no reason to use brake cleaning.

Kind regards for the response. I simply wanted to know more about AI because I'm interested in both automobiles and AI in general.
I highly recommend the 15w/40 or 15w/50 choices. I use 5w/30 and change my oil every 3000 miles; the temperature is still 70°F, but I have 200 miles to go until my next oil change.
This oil type and the filter you mentioned here were both just ordered.
In the summer:
Warmest Points: 106°F to 110°F are common.
Extreme Highs: 123 degrees Fahrenheit is not out of the question and often rises above 115 degrees.
Temperatures drop to 85–95 degrees Fahrenheit during night.
Ideal seems to be 15W/50 or 15W/40.
I refrained from purchasing the WIX, despite the fact that AI presents that filter as an invaluable asset in safeguarding yourRR.

I don't know the year of your Bosch, but Castrol 20W50 semi-syn has been really reliable in mine since 2001. Change it every 5,000 miles. So, it's never too hot or too chilly in southern California
