pre-own 100K: What oil should I use???

Hello-

I just bought a 1999 Tacoma 4 cylinders (2.7??), the truck now have 100K and do not know what oil the last owner used. I would like to use a motor oil that will help extend the life of the truck, but not sure what to use.

Syn sound good, but after reading it might cause leak...

Any suggestion will be appreciates.

Motor oil= 5-30w??

Oil Filter= brand??

 

If it does not cause leak then I am all for it. Now my oil cap read 5w-30, 10w-30 should be ok too???

 

the weight on the cap is for the most fuel efficency. thats what the truck was "built" for.

I use 10w30 in my 96 full synthetic and i havent had a problem. got it at 61K, now have 127K

 

Will do 10w-30 as you guys suggested.

Thank you!!!

 

i also ran a K&n filter on my truck..i switched to a mobil 1 filter. Works just as well.

Watch the deals and coupon section of this forum for deals at advance auto..5 qts mobil 1 and a filter for $30. Cant beat it

 

Synthetic oils tend to penetrate further than regular oils and it's a really good cleansing agent, cleaning buildup. Because of this, it can cause 'seeping'. The oil can get past certain seals and you might notice more oil consumption.

The benefits of using synthetic oils is far better than the seeping or consumption it may cause.

Chris just gave you the best advice on your oil situation, if cost is an issue there are plenty of syn blends designed for high mileage vehicles which are a little cheaper. But at a minimum you need to use a syn blend, but full syn would your best situation. Kudos to Chris for recognizing that the Toyota filter is your best money spent. IMO Mobil products work great and always easy to obtain.

 

From my experience, I bought a used 1993 Toyota Pickup with 95k miles in 2000. It currently has 234,876 miles. The oils I used have been Valvoline conventional 10w-30 and every now and then (usually when the oil was on sale) I would use Valvoline Max Life. I have always used Fram oil filters (PH3614).

I buy this stuff at Wal-Mart. Usually my oil change comes out to $15. I have always used Valvoline and Fram with no problems.

If I find something that works I usually stick to it. For my 2006 Taco, I use Valvoline and Fram oil filters.

You could always buy a box of Toyota Brand filters (10 filters) for about $50 and be good for the rest of the year.

Considering that you have a high milage vehicle (over 75k) Max Life is probably a good oil to use since it has a special additive system.

 

Another huge myth ......... Now that I am using synthetics I can drive a kajillion miles between my oil changes. FAIL ........ stick to your manufactures recommendations regardless of the type of oil being used. Also one has a better chance of blowing seals buy using wrong weights and overfilling. Some people feel that because they have a 100K vehicle They need to use 20-50. Stay within manufactures specs.

 

I used all different brands of oil, but the brand that I've noticed giving me a difference in it running/sounding smoothly, but also seeing a difference in gaining a mile more per gallon was Royal Purple (5W-30). If you don't mind spending $8 to $10 a quart, this oil is a winner by a long shot! At any rate, choosing different brands of oil is a personal preference, yet my buddies and I use Royal Purple. Good luck!

 

Just picked up a 6pk of Mobil1 10w/30 at Costco for $36.99 + tax. Not a bad price. Really over all a few bucks extra for the protection it gives vs conventional oil is minimal.

 

It was on sale last month for $10 off.

Goes on sale every other quarter.

 

Remember the difference between 5W and 10W is startup flow. Once it reaches to operating temp it's all the same 30W. Your not getting better protection. I run 0W or 5W. 148K with no issues.
