Could this be a symptom of too much oil ?? ?

Question

The garage claims on the invoice I got from them, that the techniciain added 0.35 litres of oil to my engine (1.8 ZETEC E). The level was about half way between minimum and maximum on the dipstick before the addition was made.

Now when I check the oil level on the dipstick on as level surface as I have access to, I find that the level is either exactly on the maximum mark or if above only by about 3mm or so. (The distance between MIN and MAX is about 14mm on the dipstick and this is 1000ml of oil).

Whilst accelerating up an incline I just feel that the car drives/feels different (a bit sluggish) than before it was topped up by the technician. The engine revs freely when I press the accelerator while in neutral, so perhaps it is not the engine at fault). Also wouldn't it take more than 0.35 litre of oil to cause the crankshaft to whip through the oil in the sump and cause sluggishness ? Maybe if feels different simply becuase previously there was less oil in the engine ?

What would the oil on the dipstick look like if this was happening to the engine e.g. small bubbles when cold or hot ?

Answer 1

0.35ltr of oil is not going to make any difference to the running of your engine  

Answer 2

i have seen cars come into the shop with 4 or 5 quarts more than they should have. but they still drove in. if the shop only added that little, i would look somewhere else or at least check the dipstick. typically if an engine is that far over full ( the two quarts plus that i referred to), the engine will end up blowing a seal.

Answer 3

sorry but it wouldnt have anything to do with running.. sluggish would be like tune up or fuel problem so first id add a bottle of fuel treatment and or change the fuel filter.. if that dont help it get a tuneup

Answer 4

when u checked the oillevel did u let it stand for a while first?..when the engine has been run,then stopped oil will  pour from the head back into the sump raising the level a little....

now a mate litterly filled his old car to the top with oil..when he started it oil pumped from everywhere....

a little more oil will make no differance to the power of the engine.

Answer 5

You could be right. You can drain some of the oil out when you are on a level surface. Have some new oil handy in case you drain too much. Little engines like that don't have the power to fight having too much oil. Check cold & on level surface in the morning or after it sits for a few hours. G'luck.
