Why engine oil and water mixed in mazda3

Um, most likely not good. Most likely means the block is cracked allowing the water and oil to mix. Major engine repair.

My car is using i lot off petrol why? and why is the petrol going to the engen in the oil how can that be?

it is not supposed to, they should remain separate , your petrol is just lying in your sump at this stage, check your pipes, oil is usually circulated in the engine and goes little anywhere else , your fuel goes from the tank , through the fuel filter to the carburetor or injectors , and into the pistons , the closest oil and petrol ever has to meet is the small drop of oil remaining in piston chamber before combustion ,

What is a alternative oil rated at API SG/SD oil for xj6 jaguar

i have a XJ6 4.0lt and i use the cheapest diesel/petrol engine oil i can buy ,has to be a diesel (turbo) /petrol oil so it cleans the inside of the engine ,20/50 is good enough or 10/40 and then i change the oil every 5000 miles regardless of time interval as i only use this vehicle for a sunday drive or to a classic reunion ,You do not need expensive oil you would be surprissed what they use in a garage and and what you pay for it .synthetic or natural is ok and its ok to mix them ,change the oil filter every third oil change .Cannot afford to drive this car all the time as petrol is now costing 1.59 euros a LITRE work that out into dollars

Can you mix engine oil

Hi Marsha, Many people mix brands of oil specified for either petrol engines and the same is true for oils specified for diesel engines if topping up, but it's not a good idea....It is a very bad idea to use an oil specified for one type of engine in the other. I would suggest never mixing oil manufactured for a diesel engine in a petrol engine or visa versa. The reason is that the diesel engine is dirtier than a petrol engine and manufactures of oil formulate it to have more cleaning chemicals than that used in petrol engines....Mixing the two can result in a build up of sludge which can actually block the lubrication system of the engine causing in some cases severe damage. Regards John

Diesel auto to petrol manual

I think that you can buy another car for what it would take to do that conversion.

Lets' see off the top of my head.
new heads to accept spark plugs?
new body control module
new engine control module

then keep in mind that even with all the above it still might not work because you may need proprietary parts only made for a gas engine, and you have a diesel. An engine swap may be doable but I ahve never heard of it working out in the end.
