Hi everyone!

Could someone please help me with these questions! I think my engine is the General Motors 60° V6 engine, mark "LB8". It is a 2.8 v6.

1) What type of oil to use (i live in a climate where the temperature can go below 0 in winter, but the average climate is 5-15 degrees). Should i go with a 10w-40?
2) What type of product to use? I've heard of "Castrol Edge" and "Mobil 1", but could someone tell me a better one. Price is not the issue here, i could cough of some bucks for a better quality one.
3) How many liters of oil goes into that engine?

I would really appreciate it so i can keep my baby running!

1) 10W30 works just fine. 5W30 is a little better in cold weather. you don't need a 40 weight oil unless the weather is really hot. 0C or 0F? 0C isn't that cold. 0F is cold enough to think about using a lower grade oil.

2) Walmart oil or any other house brand oil works just as good as every other brand especially if you're changing it on a regular basis. If you want to extend the oil change interval, you can use a synthetic oil.

3) Owners manual will probably say around 4-5 quarts/liters. Proper answer is to the full mark on the dipstick.

 

Thank you AlkylROC for your informative answer!

I have researched a bit and found some information as well:
1) 10W30 is fine yeah? Well the weather can go down to -10C, but for an example this year it was only 0C at minimum. So i think that maybe 10W30 is the way to go. Although i dont have any owners manual, i dont know how much the manual says. Sure the manual is like 26 years old and technology advances and information changes, it would be good to know what the manual says. But as you answered i think that 10W30 would be fine. Do you know the owners manual one?

2) Pardon me if i am being a nosyhead, but doesnt it extend the engines lifespan when using a quality oil? I have researched that M1 and Castrol Edge have been the top notch oils on the market. Although there are some racing oils as well "Purple Royal", but they cost a fortune around that 100 bucks 5 liters compared to M1 and Castrol 50 bucks 5 liters. My babe is for hobby mainly and cruising so i take good care of it or am i being too over-thinking at this subject?

3) My researched information says 5 quarts/4.7 liters. Also it says that fill it with 4 quarts and then check the oil dip by starting and stopping the engine. Fill it till the max.

 

I run synthetic oil in all my engines. The race car gets an oil change every year no matter if I make 20 passes or 100. My diesel pickup truck gets the oil changed when an oil sample analysis says it should be changed.

Quality high priced oil will not extend the life of the engine especially if you change your oil regularly. A synthetic oil will flow better of colder weather but will lubricate just as well as any other oil. All brands of oil still need to fall into specific guidelines for oil. If your engine requires a CF oil then any grade of oil with a CF or better will work just fine. They're all following government requirements. Don't get too hung up on specific brands. They all do the same thing. If you abuse your oil from racing or constant hauling/towing then a better brand may be an option but I also know a lot of racers who just use Walmart oil and have never had any problems. For the average daily driver who will change their oil ever 3000 miles, the cheapest brand you can buy will work just fine and will save you money.

Lots of good reading information here. Lots of links to look through.
