Yesterday I did the 1200km trip. Everytime I go that long trip I check all fluids in the engine before start. I topped the oil of course. When I reach my destination I checked oil again. The oil level was on the lower dot on my dipstick I wasn't happy at all as I didn't use VTEC much (3 times maybe). OK, I filled it up again and went back. I drove the same manner like before: cruising at 4k, VTEC 3-4 times as needed.
I was back at home at midnight, parked car in the garage. In the morning I checked the oil level again. It was on the upper dot... It didn't burn any oil... WTF... Would you make up the decision damn H22, please?
Some info: H22A2, 226 kkm (140 kmiles), oil semisynt Shell 10W40.

What's more I checked the coolant level. It was OK (like expected), but I found kind of ash (??) on the radiator cap... It wasn't greasy, no oil in the coolant, but some of this wet ash.... What could it be? Is it a symptom of headgasket giving up?
Any ideas appreciated.
Thanks

 

more info about fuel (maybe this is an important factor?)

way there- 98 octane fuel
way back- 95 octane fuel

Can different fuel burning temperatures cause oil to dissapear?

 

higher octane fuels combust at higher temperatures therefor stopping engine knock/preignition on high compression engines. Mines run on 98 everyday and ive never had an oil burnig issue.

I would jack the car up take a good look around underneath and around the oil pan, make sure you dont have any oil leaks anywhere.

is that the normal fuel types available at gas stations??? if so you bastard, damn ca and their damned 91 octane

 

Those are normal fuel grades here (Europe/Poland). We have also 99+ fuel made by Shell which is supposed to have 102 octanes but it's pricey.
But on the other hand would be be willing to pay 4$ for gallon? Doubt it...

 

aw yes, i forgot how much more per gal fuel is in europe...i guess 91 aint so bad...

They call it VPower here but I believe it's the same product.

Welcome to the EuroCommunism...

 

Sounds about right EuroCommunism

I was wonderig if it is the same product but Im not 100% sure because of the rating of 98-99oct on Optimax but I think the Vpower might be 'better' car-food because of the higher Octane Rating of your V-Power stuff
