I use Millers Nanodrive CFS 5W40 NT+, it`s expensive but I drive my Porsches hard and track them, changing the oil before each trackday.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Sorry, another what oil query but related to mileage in my defence..
Car coming up for 12 months in my ownership and about to turn 110,000 miles. Due it's annual service. I have only done 3000 miles or so this year.
Car has been running on 0W 40 but was wondering whether to change to 5W 40 (or another rating?)with the higher mileage?
Thoughts please n ta.
I would advise 5W/40 mobil 1 oil .. it's what we would be using any ways ..
You can go 10W/50 but i would prefer a step at a time instead of a big jump so perhaps start with 5W/40 .
Gulf Formula GX 5w40 on sale at ECP. 20 litres for £37 if you use the code BF19.

The only difference between a 0w-40 and a 5w-40 oil is the viscosity at cold temps. The 0w-40 flowing easier when cold but once up to operating temp they will be exactly the same.
Mobil vs Shell vs Gulf vs Petronas vs Castrol vs Millers!!
Going to go 5W 40 but what brand? Surely they are all similar spec?!
Some great Black Friday deals on some..
