- 2009 MAZDA2 NEO 1.5lt Auto 5Door JMODE10Y1901426XXX. 203,500km
Mazda2 DE 1.5L MZR ZY-VE Engine, factory standard no Modifications.
I'm running 5W40 Shell Helix ULTRA GTL Full Synth ACEA A3/B3, A3/B4 SP DEXOS2 etc with 6% NOACK. Have multiple days 10 Deg to over 45Deg C in summer here. The 5W40 does not require a Top Off over 5,000km
Have run Shell Helix ULTRA GTL Full Synth 5W30 ACEA ECT C3 SN etc ?% NOACK in Winter 0 to 25 DegC typical. The 5W30 required a Top Off of 100ml -150ml over 5,000km.
The car does Plenty of Stop Start City Driving along with 2Hr & 6Hr High Speed Full Op Temp runs sitting at 120km/Hr door to door
Have purchaced some Shell Helix ULTRA GTL Full Synth 5W30 GF6A ?% NOACK to try for the Winter so will see how it goes WRT Top off over 5,000km.

10W50 20W50 & 15W50 as Max Ambient Op Temp of 50 Deg C
Pg8-15 High Temperature weather conditions require higher viscosity engine oils for satisfactory lubrication.....particularly under the hash climate conditions existing in Australia and New Zealand.....Use ISLAC GFII or GFIII or API Service SG or Higher
Pg10-5 Engine Oil Capacity with oil filter replacement 3.9lt
Pg8-16 Distance between L & F on the dipstick = 1.0lt
######
Mazda 2's run Hot. 100-102 Deg C on OBDII PID for the thermostatic Fans to cut in in the stop start driving following following the 80km/Hr or 120km/Hr full Op Temp Runs...
What are others seeing WRT for High Ambient Temperature Operation? & Oil volatiles evaporation.
What is the NOACK % of the Oil you are running?
######
Could be worse
.....I could be at Cymbric Vale Station Australia, Jan 2026 10 Days over 47 Deg C Highest Temp Day 51 Deg C
Wet Change has occured there for February 2026 320mm of Rain ie 1&1/2 years worth of Rain
