F150 supercrew 2001 with 150k miles want to switch

Just use whatever is recommended by Ford. It should show u on ur oil cap or on the sticker that's under the hood. All Ford vehicles use either 5w-20 or 5w-30

Hi,
Pennzoil, 5-30.
I do not work for Pennzoil.( smile)
85k is reasonably low miles for the year of your Ford.

Some people would say no, some would say yes. Some, like me would say no. The choice is up to you. If you change your oil regularly, you should never have a problem with the bottom of your engine. Or the top either for that matter,. Some people get started with synthetic and never stop. I have heard pros and cons about it. I used before, and I use it in my bike. The stuff is slippery. The weight you chose is good for hot weather, winter time might call for 5w30. One of the bad things about it is, it doesn't break down like conventional oil. I don't know if that is good or bad. I'll let you decide. Hope this helps.

Synthetic oil won't break down as quickly as conventional oil, gives better protection and longer life. Excellent product, I Strongly suggested for those out there who forget to do their oil changes regularly or courier/ work vehicles.
Heres the link to an explaination from Castrol

I use conventional Oil in my jimmy with 5% of Lucas engine oil treatment and service the engine every 3,000 miles. I find it to costly for the Synthetic oil every 3,000 miles, and as for the high mileage oil you can buy. The high mileage oil has a higher fluid retention like adding Lucas engine oil treatment to any conventional oil, so you decide on what type of oil you like to use in your engine.
Good luck and hope this helps.

5 qts of 5w-30.

I personally prefer MOBIL1 brand ..You can decide as per your wish..


SOME ADDITIONAL INFORMATION:

There are many grades of oil weights whichever you want to call it. Heres how it works
Oils main job is to keep the engine clean, lubed, running cool ect. The grade usually 5w20 5w30 or 10w30 ect. Theres many of them as well which can be consfusing at times. Oil weight is measure by cold and hot . For ex: 5w30 The 5 weight is when the oil is cold and 30 is the weight when its hot. The reason being is the the less the weight when its cold the easier the oil can get to the top of the engine and lube it to prevent cold engine damage. Once its heated up its a 30 weight and is thick enough to protect your engine.( most engine damage is caused when the engine is cold )You should use the proper grade that your engine calls for. Being toyota its probably 5 or 10w 30.If you live up north i would recommenda 5w30 weight.You can easily find out which grade you should use by your owners manual or under the hood on the oil cap. However there are synthetic oils as well. Synthetic oils have man made additives to help the engine run cooler, the oil is naturally slicker to help it move around easier and boost performance of the engine resulting in better mpgas well. They have alot of additives to prevent engine wear ect. One good thing about a synthetic oil is you can go longer on the oil change. Instead of the normal 3,000 miles oil change you can go 4 or 5 k. Theres also synthetic blends. Which are good too but youll have to read about it more to decide for yourself what you think you need. Synthetic oils are better for someone who travels alot or puts extreme conditions on an engine such as idling for long periods of time stop and go traffic its really good for anything to be honest.. I would recommend using synthetic if you decide to keep the car for a while. It has many benefits.

do not use any fuel additives at all. and only use 87 octane fuel nothing higher. 4.6 and 5.4 ford engines do have a pinging sound especially with a load. but it is normal

The motor oil from the factory is motocraft synthetic blend 5w-30 for normal conditions and motocraft synthetic blend 5w-20 for cold environments. But any synthetic blend or full synthetic of equal weight will do just fine and you will require 5 quarts of oil. DO NOT USE A THICKER WEIGHT OIL, OIL ADDITIVES OR NON SYNTHETIC. Thicker oil like 10w-30, 10w-40, 20w-50 will not be thin enough to lubericate the tighter clearences of the motor and coventional oil breaks down faster than a synthetic blend or synthetic. And be sure to change the oil every 5,000 miles

basically depends what climate you are in... 5W30 is pretty good for cold climates... 10W30 usually seems to work best tho

They say you can, but remember, not a good idea to switch back if you change your mind later. Personally I'd go with 5w30 for winter then maybe 10w30 or 10w40 for summer. All kinds of arguments for and against synthetic, vs standard. personally I prefer standard & change at proper intervals.

The oil you took out was probably a lighter weight. A heavier oil will show a higher oil pressure. Make sure you are using the proper weight for the temperature conditions in your part of the country.
