Why no year make model.....?
I would stay away from that oil, A stupid company name, snake oil "additives" and incorrect use of SAE oil grading.Didn't know sae had 0W2
Is that a typo?
Over in the U.S. that engine (Toyota? Nissan?) would likely have spec'd an API SL /ILSAC GF-3 5W30 with HTHS >3cP.My brother has an old car and currently has a 120 mile daily highway drive.
He asked me what i could do to make it absolutly as fuel efficient as possible.
I said it probably wont make a lot of difference and maybe try a simple thing like putting a little more pressure in the tyres.
And if you want to make it extreme take a thinner engine oil and trans oil but there are hazzards attached to doing this and i wont recomend it for the very smal gains.
He however wants to try it so i looked into some oils.
Its a 2004 1.6 16v gasoline engine with 110hp and 5 speed manual trans, oem spec oil is 5w40.
Currently theres motul 5w40 in it which has a the following specs:
Viscosity grade SAE J 300 5W-40
Density at 20°C (68°F) ASTM D1298 0.851
Viscosity at 40°C (104°F) ASTM D445 85.4 mm²/s
Viscosity at 100°C (212°F) ASTM D445 14.2 mm²/s
HTHS viscosity at 150°C (302°F) ASTM D4741 3.7 mPa.s
Viscosity Index ASTM D2270 172
Pour point ASTM D97 -36°C / -33°F
Flash point ASTM D92 230°C / 450°F
Sulfated ash ASTM D874 1.1% weight
TBN ASTM D2896 10.1 mg KOH/g
I looked into ravenol 5w20 SFE which has the following specs, i liked it because i think its a pretty ''thick'' 5w20 and has a HTHS of 2.9
Density at 20°C kg/m³ 843,0 EN ISO 12185 Colour braun visual Viscosity at 100°C mm²/s 8,5 DIN 51 562 Viscosity at 40°C mm²/s 47,2 DIN 51 562 Viscosity index VI 160 DIN ISO 2909 HTHS at 150°C mPа*s 2,9 CEC L-036-90 CCS Viscosity at -30°C mPa*s 3640 ASTM D5293 Low Temp.

These engines are known to be pretty bulletproof , i used to own one and did a lot of 120mph prolonged highway runs where oil temps would reach 285f 140c, that was also on 5w40.
Does anybody have experience with switching to thinner oils? Did you encounter problems with this? Normally you can pretty safely switch from 5w40 to 5w30, however from 5w40 to 5w20 is a large step.
Basicly as long as the oil pressure is stable and high enough i dont forsee any real short term problems, except maybe some more oil consumption. (normaly these engines use absolutly 0)
I told him its a pretty large risk to take suchs large steps for almost inmeasureable amount of fuel consumption reduction. But he wants to try it.
You can get these engines for around 100 euros at local junkyards so its not that big of a risk. As i said they normally never fail so they are not that sought after.
This. Most people I know don’t give a second thought to tire pressure unless the TPMS light comes on.No when the term “properly inflated” is used. A lot of drivers are running on under inflated tires due to ignorance or laziness.

The high HTHS 5W30 is NOT going to save you fuel. I would got with a Mid saps Mid HTHS oil like aFor my BMW i will probably order a 20l jug of Fuchs 5w30 LL04 spec oil because it consumes a lot and from germany this is pretty cheap at 4 euros a litre.
I will probably use this like a fleet oil for my families vehicles and some friends of mine. All are older cheap early 2000s pretty regular low horsepower verhicles.
This is a 5w30 with a HTHS of 3.5.
I am sure that this will not cause any harm to the engine. Ive read more stories on forums where unknowing shops just threw 5w30 in it because they have it in bulk and the engines ran fine.
Switching to 0w20 would be a different story however.
It's not a good idea to stray away from the OEM spec for two reasons:Its a 2004 1.6 16v gasoline engine with 110hp and 5 speed manual trans, oem spec oil is 5w40.
