5W30 is a viscosity rating, In simple terms resistance to flow. 10W40 is a thicker oil in extreem winter climate you could experience hard stating.If you use a synthetic or partially sythetic oil you will be better off.
i tried it in my 95 Monte Carlo 99,000 miles.it triggered service engine light to come on.going tomorrow to put 5w30 back in it.
In newer model vehicles it is important to use the correct viscosity oil because the engine has been made to properly flow oil of a specified weight. I've seen heavier oil put in new vehicles by ignorrant techs. and the oil can not make its way to lubricate the valves and wears a good motor fast. If you hear ticking noises you better change with new oil qiuckly and hopes the motor runs smooth again.
no. This will cause problems in the transmition.
10w40 in summer and 10w30 in winter. Any heavier oil will cause lifter noise. I have also found the engine on 10w40 will only tolotare about 1/2 quart of lucas oil.
no Yes, it can cause the belt to squeak and slip.
No. It is illegal, will cause a check engine light and running problems.No. It is illegal, will cause a check engine light and running problems.
Honestly yes. it can cause major problems and all together it could cause your engine to blow. so id change them they arent that hard.
Yes, If vehicle overheats it may cause freon (refrigerant) to blow out
Incorrect timing can cause several problems. One of which is high idling. 5000 rpm sounds high though, there may be other problems as well.
It could cause engine damage. We had somebody put 10W40 4 stroke oil in the injection oil tank of a 2 stroke sea doo pwc and it ran for less than an hour before there was significant engine damage. He is now forever known as Captain 10W40.
The engine overheating, or a faulty gasket, or problems with hot spots in the engine.
If the converter is partially clogged it can cause the engine to overheat which can cause serious problems. Other than that if will not harm the engine.
