#1851709 - 04/10/10 01:35 AM Oil for a Toro 6.5 HP mower?

I'm helping my sick uncle care for his house and yard. He has a newer Toro "Guaranteed to start" "Personal Pace" 6.5 hp lawn mower. He does not have the owners book and can not tell me what kind of oil to use. What oil would be good for this engine? I'm using Castrol GTX 5w30 in my Honda mower and for the last 3 years it has ran smooth with no problems. Can I put the Castrol GTX in the Toro? Also how many ounces does it take? Many thanks for the help!!!

I would search toro.com support with the model number for the mower to see the owners manual.

https://homeownersolutions.toro.com/portal/server.pt/community/product_center/225#manualsResultPage

Here is the info from a 2009 walk behind mower owners manual - with a B&S 6.75 ft/lb torque engine-
(another model with a 6.5 HP Tecumseh engine says the exact same thing)

Remove the dipstick and check the oil level
(Figure 12). If the oil level is below the Add mark on
the dipstick, slowly pour oil into the oil fill tube to
raise the oil level to the Full mark on the dipstick.
Do not overfill. (Max. fill: 20 oz. (0.59 l), type: SAE
30 detergent oil with an API service classification of
SF, SG, SH, SJ, SL, or higher.)

I'm sure the castrol would be OK, but this would be better..

30W is second choice if your engine is a B&S. Their #1 recommendation is 5W30 synthetic for all temperatures between -20 and +120. They sell a 5W30 sythetic oil that is still an SL formulation under their own name.

Above 40F use SAE-30 below 40F use 10w30 I would never use 5w30 in an air cooled engine. Remember B&S recommends using THEIR brand 5w30 synthetic NOT another brand. I have had great results using Napa SAE-30 and 10w30 in my air cooled equip.

I asked the same basic question last Saturday and got some good input. Here's the link:

http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1843369

I selected PYB SAE HD-30 which I got for $2.49/quart.

I used M1 5W30 in my mower for about 8 years, until I ran out of my old stock M1 that was SL formulation. Now, I am using M1 High Mileage, which is still SL formulation. I notice that the Amsoil 10W30/30 for small engines is an SL formulation, as is the well- thought of German Castrol 0W30.

My mower engine, a Honda 160GCV, still, after 10 years, burns no oil in a one year, 55 to 60 hour OCI. I am thinking of getting a few quarts of German Castol and trying it in my mower and other OPE.

Do not forget that, at operating temperature, a 0W30 is just as thick as a 5W- or 10W30 oil.

Yep. There's a whole thread on 0W-xx oils at the following link:

Thanks guys! I think the Castrol GTX should do the trick! Maybe GC?

I would definetly use GC 0W-30. I think it would make an excellent OPE oil.

I have found my 6.5 Toro personal pace engine sounds the best/smoothest on Pennzoil straight 30 weight.It had some kind on knock on the GC.

Lexus 114 : These little air cooled engines shear down milti-grades very fast , GC has VII improvers and it will shear down . Always go with the least amount of VII oils for air cooled engines. That means no 0w30 or 5w30 for air cooled engines, the knock you heard was from GC thinning down and losing fluid film thickness.

I believe your right,but why do they recommend 5W-30 Synthetic oil ? That baffles the [censored] out of me. I remember also around 30 some years ago,They used to recommend non detergent straight 30 weight oil. Reason being the detergent oils would foam up inside their,I guess they figured out a way around that too.
