Engine oil MOTUL or OEM Audi

However my "go to" oil in the last two oil changes was the Motul Specific 508 00 509 00 0W-20.

Last change , used Motul 8100 0W - 20 Full synthetic

Motul 8100 X Clean 5W30, used by reputable specialist Mini garages here in the UK and is in my 2018 JCW.

For such a climate as Mexico I'd stay away from 0w-20 and go at least to 0w-30 or 5w-30, last one being the OEM afaik.

Tbf my specialized mechanic put 5w-40 LL-04 Motul in mine for years and it's been blissful.

Motul gamit ko ramdam ko ang arangkada at tahimik makina.

Shell Advance Scooter naman d ko ramdam yung arangkada nya kasi medyo may delay at ambilis mag bawas ng langis. Unlike sa motul na low oil consumption lang sya d sya ganun kalakas mag bawas ng langis.

Ive been using 5w40 for 100k miles and my engine is happy as can be. It actually is noticeably smoother with thicker weight

The one that seems to have made the greatest difference (non-tracking) is the one referenced below in either 5w50, 5w40, or the two of them mixed together. Per the relevant gauges, the 996 runs a bit cooler and the viscosity (via oil pressure readings across running temperatures and times) stays higher.

OEM oil is made by cheapest bidder who was able to fill the minimum requirements by the already cheapskate GM.

my 2 cents - use MOTUL DEXOS 2 SPECIFIC. Or some other premium oil. Oil is the most important fluid your car has. Cheaping out on it just stupid.

New Audi do not have the oil sticks to check the oil levels, so they always under pour the engin oil in the car, my q8 is been serviced by Audi and past 2 years I have to top up oil (which is free as car is under warranty) but last month I got pissed and asked them to top it up to max and car runs much smoother and fuel consumption for 1 full tank is 130 km better.

This sub loves to praise motul, but it caused me to foul up my spark plugs and have misfires. I tried both the 5W30 like the manual calls for and 5W40, but shortly after I changed to motul my plugs fouled up. I replaced them, they fouled up and misfired again. I tried it a third time cleaning the MAF sensor, checking if the plugs were torqued okay, checking the seal on the coil packs, etc... still fouled up. I finally guessed it was the motul and did an oil change away from motul and swapped the plugs again. 14k later no fouling.
